Which equation represents the axis of symmetry of the function y=-2x^2+4x-6
A y=1
B x=1
C x=3
D x=-3
Is the answer C?
1. B
2. A
3. D
4. B
5. D
6. B
100%
Lesson 2: Quadratic Functions
Algebra 1 B Unit 4: Quadratic Functions and Equations
1. B x=1
2. A (3,-2)
3. D (-2,15)
4. B (It looks like a U on the left side of the y axis)
5. D y=2x^2+8x-5
6. B y=19x-10
The final score is 6/6 (100%).
1. B
2. A
3. D

--
1. B. x=1
2. A. (3, -2)
3. D. (-2, 15)
4. B. *graph*
5. D. y=2x^2-8x-5
6. B. y=19x-10
7. D. -5
8. C. The functions have the same minimum value.

6/8 for me
And 6/6 for all the answers but the last two if you don't have them!

Thanks @awnsers!
for arca, the answers are...
1. B x = 1
2. A (3, -2)
3. D (-2, 15)
4. B it is a graph, but here's the question "Which graph represents the function y = 3x² + 12x –6?" + there should be a curve that covers a bit of the - in -16.
5. D y = 2x² + 8x – 5
6. B y = 19x – 10
@awnsers is 100% if anyone is wondering:)
(For connexus)
the axis is x = -b/2a = -4/-4 = 1
So, B
-2x^2 + 4x - 6 = -2(x-1)^2 - 4
You could easily see that x=3 is wrong, by checking f(x) at values equally spaced from it, as f(2) and f(4). If x=3 is the axis of symmetry, they should be the same. But,
f(2) = -6
f(4) = -22
@awnsers is correct for GACA

Thank you, on behalf of the people of Wakanda
~For TCAH students (and whoever else wants to read this XD)~
@awnsers is correct but for me, there were only 5 questions so the answers to that are: B, A, D, B, D.
Actually, nope. You up there buddy, ^^^ @CAstudent are wrong.
I'm in normal Algebra 1, not GT Algebra 1 (not sure if there's a difference in test answers), and for me, @awnsers is 100% correct.
sometimes different states have different questions, im in Colorado connections & for me awnsers was right. thanks awnsers!!
Guys, @Connections Academy Student is only 100% in HONORS ALGERBRA.
HONORS ALGERBRA ANSWERS (In full) Are…
1) X = 1
2) (3, -2)
3) (-2, 15)
4) B (They’re graphs…)
5) y = 2x^2 + 8x - 5
6) true
Pls just use this to check
But I know most of y’all are just gonna ignore that lol
This is only for honors algerbra
For California connections its
1. B. x=1
2. A. (3, -2)
3. D. (-2, 15)
4. B. *graph*
5. D. Y=2x^2+8x-5
6. B. Y=19x-10
The staar test is non existent this year 🗿
YAY!! no STAAR

"broke in primogems" got me 100 % in 2022 thank you sm
1. x=1
2. (3,-2)
3. (-2,15)
4. the line starts from the top left going down and then curving up again, the graph also shows mostly the negative numbers
5. y=2x^2+8x-5
6. TRUE
YOU'RE WELCOME, I HAD TO GET 2 WRONG ANSWERS FOR THIS, it's my fault really I mean I should've paid better attention to what the answers were but ngl I am a little disappointed that I did this to myself again T_T
Oh! Havem was 100% correct for Nevada Connections
joey is 100% correct
broke in primogems is still right
thanks broke in primogems!
For people with 8 questions 100%
1. x = 1
2. (3,-2)
3. (-2,15)

u are right my dude
thx guys
@CJDizzy03 is right for Texas connections :))
i only have 5
@answers is right for Houston too
I love how everyone ignored the math teacher that came on here LMAOOO
"broke in primogems" is right for arca!
@ Havem. Thank You. Oregon Connections is correct with the answers.
thanks CJDizzy03 🙏🏾😓

Congratulations, Everyone! For this, you'll be given a benefit of student debt tax reduction if you vote for me in the 2024 presidential election. Remember, your vote counts to me and my Vice President Kamala Harris.
Sincerely,
Joe Biden
I'm sorry, but Joe Biden is currently the President of the United States and there is no evidence that he is making this statement. As an AI language model, I do not support any political candidate or party.
yay 100%
