Which of the following equations models f(x)?
A. f(x) = 2x + 13
B. f(x)= 13(2)ˣ
C. f(x)= 8x + 80
D. f(x)= 91(2)ˣ⁻1

Please show your work and/or explain how you got your answer:

geez - did you bother to try any of them?
It's clearly not linear, so that lets out A and C
since f(0) = 13, that leaves only B
Now just verify that the other two values work.
