This table shows some values of function f(x)
| x | 0 | 3 | 5 |
| f(x) | 13 | 104 | 416 |
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:
PLEASE HELP!!!
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.
