Question

What is the exponential function modeled by the following table?

A) f(x) = 2^x
B) f(x) = 2^x + 1
C) f(x) = 3^x
D) f(x) = 3^x + 1

Answer 1

we have given the values of x and f(x) in the table we have x=2 and f(x)=5 for this if we plug x=2 in option f(2)=2^2+1=4+1=5.

for f(3)=2^3+1=8+1=9.

f(4)=2^4+1=16+1=17 .so the exponential function modelled by the table is option B)f(x)=2^x+1.
