Illustrate an educational scene depicting a student of South Asian descent, studying quadratic functions and equations late in the night, surrounded by notebooks and a laptop. An open textbook with sketched graphs of quadratic equations and functions lies next to him. The glow of the lamp and the laptop screen cast an inviting light over the whole scene. Make sure the image doesn't contain any answers or text.

Lesson 10: Quadratic Functions and Equations Unit Test answers please! I need the right ones

OML WHO ON EARTH IS RIGHT CAUSE THE THUMBS UP ARE VERY LOW ON ALL OF THESE

bro, why does no one just right the letter answer AND the question. that would help everyone so we know if we have the same test or not.

Guys you realize that you have to say the exact answer you got so people can see if the question is correct?

Lesson 10 Unit 4: Quadratic functions and Equations Unit Test Part 1

1) Domain (-infinity, infinity) Range (-infinity, 0)
2) It is shifted 5 units down

4) y= -6x+8
5) two solutions
6) one solution
7) D linear
8) quadratic
9) 580 ounces
10) 184.00 seconds
11) Reaches a maximum height of 242.56 feet after 3.81 seconds
12) two solutions: x= -10,2
13) graph- there are two solutions: x=-+1
14) 2, 1/2
15) x= -5, 2
16) 12 m
17) 225/4
18) -11.56, 1.56
19) 1.59, 4.41
20) -1, -3
21) exponential

I hope this helps some of the confusion above. These are the answers for Indiana connections academy Lesson 10 Unit 4 100%, I'm not sure if they are valid for any other school or state, but I wanted to help because I got a C on the test cause of the jumble of answers above.

Don't use any of these answers! you will end up with a bad grade, they change the answers so my best advice is to individually search up the answers, it worked for me, I only got 2 wrong. But be careful when you look for answers, they aren't always correct. Good luck everyone :P

I am from TCAH and I just took the Unit 6 Lesson 11 Quadratic Functions and Equations Unit Test using the answers provided by a previous post. I recieved a 10/16. I will provide the correct answers so your grades do not suffer.

1. D (the graph that appears the same as the original, but is higher on the y-axis)
2. B (x^2+3x+2=0)
3. B (I don't know how to type this equation with the proper symbols)
4. D (-1,5)
5. B (one real solution)
6. C (0.83 seconds or 3.55 seconds)
7. A (30 inches by 45 inches)
8. A (x=5 or x=-2)
9. B ($310 at $2 per kilogram)
10. A (the graph with its vertex at {0,1} and line with y-intercept of 2)
11. C (x-1)(x+5)
12. B y=-5(x+1)^2+6
13. False
14. True
15. False
16. False
17. (I will provide which form would be most helpful, you can come up with an explanation)
a. Standard Form
b. Vertex Form
c. Vertex Form
d. Standard Form

I need the answers for connexus

the questions are usually different for each test so 🗿

UPDATE 10/20/2021

ME AND @fools have the same test order, but sum of the questions are differently written, be advised when copying

Also, for most of the questions on the test, you can easily use Mathway,
(the best digital calculator that has ever been created, in the history of mankind)

if you ever feel stumped on a question, and you can't seem to find it on brainly or THIS website (jiskha), just use Mathway or guess..

chances are, you're only gunna guess on about 3 of the questions during the test, and out of those 3... you might get 1 correct, resulting in a not so bad grade.

With that being said, stand up, walk around your crib.. go outside for 30sec.. come back, and finish the test..... you got this 😤😤😤

And as always, Happy cheating everyone

!WARNING! SOME ANSWERS ARE DIFFERENT DEPENDING ON WHERE YOU ARE FROM AND WHAT TIME YOU LOOK AT THIS!

everyone is wrong lol

Oh yea and I’m in algebra 2

hi uh i’m in tennessee and i want to say that i assume that just everyones questions are a bit different since i used those answers and made a 52...no hate to you but thought i’d say that for anyone else you may see this lmfao.

Did any of you do it yet? I really need answers

please whos right?

None of these match my test. Wtf

those are the answers to Unit 3 Lesson 10 Functions, Equations, and Graphs Unit Test from connections, in Algebra 2a

Are these

for unit 4

Can people post their questions and then If we have some of those questions then people can eventually find the answers.

this is the last thing i have to do in algebra to pass and idk how to do any of it and its due by tomorrow so like cheers. idk what the right answers are

does anyone know the answers to Algebra Unit 4 graphing quadratic for Connexus

you guys are all wrong cause we all have different orders in the test. your welcome:)

FORGOT, BTW MASSACHUSETTS CONNEXUS SORRY

you guys know that test are different for each student right? you guys are straight up dumb.

alright guys: I dont have all the right answers, but i got 15/21 (71.43%) with "gorgi"s answers. Not all of them were the same as mine, but I chose the answers that were the most similar (for example: gorgi said 4m, and none of my options were that so i chose the closest one which was 3m) i got that answer right. I really really want to help you guys, but im afraid of putting the answers and then getting told that i made you guys fail so. Just do what works for you

shy is wrong

Look at my name

Can anybody give me the answers to Unit 3 lesson 22( unit test )

Umm does anyone still have the answer for Lesson 10 Quadratic functions and Equations unit test ?

same sierra

so i cant find it:( sorry yall

Here is a tip for ya'll normally the correct answers have a bunch of likes so just look at the likes down below and then you can tell who is right. But if there are like 3 likes and 2 thumbs down find different answers.

@😀😀😀😀... You are correct. Out of all the students who actually take Connexus, the test is mainly all the same for everyone other than how some (or sometimes a lot of) questions have numbers that are changed. For instance, some people in Texas could have this equation on their test: 2+2

While I (In Tennessee) could have 3+3. This example should pretty much explain that not all the tests are the same but most are overall similar in some ways. Hopefully this makes sense and can help when you can't find your test answers. :)

these are all going to be different not one will work for everyone they change the answers all the time for math

Can I type yet

Wife I going on here? So many different answers

Dam

If you made it down here this far you might as well just stop looking for answers and try your best, we don't know what the heck we are doing.

yes

I got a 14/21 using “hope this helps” response. Which I’m not completely mad about. I used it for unit 5 lesson 10 unit test on tcah.

5.10.1 Quadratic Functions and Equations Unit Test Part 1

answers plz. and right them out?

What's poppin, just took from what sav said. They were mostly right, but some stuff didn't relate to my test. For Unit 3, Lesson 10 of 9th grade Algebra, these are the answers.

domain: (-infinity, infinity) range: (-infinity, 0) it's the one with the blue line perfectly aligned with the x and y axis point (the cross thingy).

It is shifted 2 units down.

160.56 m

y= -4x + 10

two solutions

one solution

linear, with the blue dots at the top of the graph.

quadratic

580 ounces

3 s

Reaches a maximum height of 242.56 feet after 3.81 seconds.

two solutions: -6, 2

There are two solutions: x = +2

2, 1/2

6, -4

4 m

81/4

1.1, -9.1

-10.35, 1.35

-1, -3

exponential.

These are the answers for 9th Grade Algebra. Unit 3, Lesson 10. In Connexus. Good Luck. -glorg
