Question

Question in the comments, Please help me!

Answer 1

So same kind of process your f(x)=56 and you x=8 so you have the equation xk=f(x) can you try and plug in the numbers? I know you can!

Answer 2

I don;'s get it,
f(x) = 56, but then x = 8?
How am I supposed to plug those in..?

Answer 3

Into your equation the f(x)=xk equation what goes in your f(x) part?

Answer 4

You said it!

Answer 5

Ohhhh! I get it now! The correct answer is D.14!

Answer 6

Yes!!!! Good job!!! :)

Answer 7

I have 1 more I need help though!

Answer 8

Ask away! :)

Answer 9

Well this has to do with consistant slopes which ones can you knock out right away?

Answer 10

Like if you plug in x values which would be constant change for 2 of those instantly

Answer 11

I got no idea..

Answer 12

Can you think of it in a slope way?

Answer 13

Are you good with slope?

Answer 14

I guess..

Answer 15

Its okay okay think about the second and third options this is kinda tricky to explain

Answer 16

If you plug in 0 1 2 for x what would you get for the 2nd function

Answer 17

I think the correct answer is A.y=4/x

Answer 18

Yes because if you plug in x values 1,2,3 your not getting a constant rate of change 4/1=4 4/2=2 4/3=4/3 we dont know what this function is decreasing by because its not constant

Answer 19

Unlike 7x if you plug in 0,1,2 for 0 you will get 7,14,21 you know the constant rate of change is 7

Answer 20

So, A is correct?

Answer 21

Yes

Answer 22
