Exponential Functions Examples
Example 1
If a function contains the points (1, 3), (2, 9), and (3, 27), is it most likely exponential or linear? 
Example 2
Solve for y: 3^{(2x + 4)} = 9^{y} 
Example 3
Solve for x: 7^{(7x – 3)} = 49^{2x} 
Example 4
Solve for x without using a calculator:

Example 5
Find an exponential function f (x) = Cb^{x} that contains the following set of points: {(1, 4), (2, 8), (5, 64)}.
