Question

Select the correct function that represents this data

Answer 1

Answer: A

Sustitute one of the inputs into all of the equations and see if you get the respective output. I will use the point (0,2).

A. f(0)=8(0)+2

     f(0)=2

Option A works!

B. f(0)=8(0)-2

    f(0)=-2

Option B doesn’t work.

C. f(0)=8(0)

     f(0)=0

Option C doesn’t work.

Since option A is the only one that works, the correct function is A.
