# Evaluate Functions for Given Value of X.

Evaluate the functions for th 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 (i.e. is there a pattern in the change, did the values double, or triple, increase by a certain factor, etc.

1. f(x) = 3x -2

2. f(x) =x2 - 5x +6

3. f (x) =x3 -3x2 -2x + 1

4. f(x) = ex

5. f(x) = log x.

#### Solution Preview

1. f(1)=1, f(2)=4, f(4)=10, f(8)=22, f(16)=46

f(x) increases by a fixed rate 3.

2. f(1)=2, f(2)=0, f(4)=2, f(8)=46, ...

#### Solution Summary

Functions are evaluated for given values of X. Patterns are also investigated.
