Question About Evaluate Functions

I need to evaluate the functions for the values of x given as 1, 2, 4, 8, and 16. Describe the differences in the rate at which each function changes with increasing values of x.

f(x) = 3x + 2
f(x) = x^2 + 5x + 6
f(x) = x^3 + 3x^2 + 2x + 1
f(x) = e^x
f(x) = log x

Solution Preview

f(x) = 3x + 2 =>f(1)=5, f(2)=8, f(4)=14, f(8)=26, f(16)=50
The increase rate of this function with increasing x is constant and is equal to 3

f(x) = x^2 + 5x + 6 =>f(1)=12, f(2)=20, f(4)=42, ...
