Question

What is the exponential function modeled by the following table?


x f(x)
2 10
3 28
4 82
f(x) = 2x
f(x) = 2x + 1
f(x) = 3x
f(x) = 3x + 1

Answer 1

To this kind of problem, the fastest way is testing
for example
If f(x) = 2^x, Now, plug in x =2, f(x) =2^2 =4 , not =10 as given information --> f(x) =2^x is NOT the correct one.
You do the rest, please
