1. The ordered pairs (1, 1), (2, 8), (3, 27), (4, 64), and (5,125) represent a function. What is a rule that represents this function?
Y = x
Y = 4x
Y = x^2
Y = x^3
I don't know how to solve this please help!
1) A
2) A
3) B
4) D
100% correct
I have 19 questions
i have 19 questions!?!?!
theres 19 on the test
I have 19 questions too.
The easy way to do these is to look at it and try each of the answers.
For example, 2*1 is not 8 for a answer.
2*4 is 8 and that's ok but 3*4 is not 27.
For answer c, 2^2 = 4 and that's not ok.
Finally, 2*^3 = 8 which is ok. Next, 3^3 = 27 and that's ok. Next 4^3 = 64 and that's ok so I'd go with y = x^3. You can check out the last ordered pair to make sure 5^3 = 125.

thx @YouDon'tKnowMyNameXD
He/She is right I got 100%
Mine has 19 questions PLEASE HELP!

15. B
16. idk this one But I believe this is not a function as (-2,6) is out of shape and does not form a perfect line.
17. Not sure
18. ($8.25 x $11.00) = $90.75 - 5.00 = 85.75
19. Not sure
Hope this helped
some have 4 and some have 5, mine has 4 questions
for different states its differenttt!!!!
Are they correct
No they are random
dcadb
YoudontknowmynameXD is right
Your the best Meh! Thanks it was 100% right! Same I was like you don’t know my name there are 5 questions! But thanks both Meh and you don’t know my name!
For honors students of SCCA, the answers are:
A (Dots going up, in a stair-like way.)
Yes
Linear
y=x^3
A=4r^2-pi r^2
Mine has 30 help please
Please provide the unit and lesson number for your quiz so I can help you better.

There are 5 questions on this quiz....

100% correct I just took the test....
WRONG!!!
This isn't a test, it's a quiz- Lesson 3 Unit 5, mine has 4 questions and A, A, B, D is correct
Well for this problem what you would do is you would take each set of ordered pairs and substitute the x coordinate for x and the y coordinate for y.
If for all 5 ordered pairs a function works, then that is your answer.
For example take the first one.
With the set of coordinates (1,1)...
the first function would work because 1=1.
Lets try substituting another pair for the same function. (2,8)
8=2.
Since that is not true, you know that this function is not true for all the ordered pairs.
Try this method for the rest of the functions. I hope this helps!
