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) = 9y

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) = Cbx that contains the following set of points: {(1, 4), (2, 8), (5, 64)}.
