Graphing Exponential Functions

Graphing Exponential Functions

An exponential function is of the form n^x, where n is a positive number, and which has been raised to a power. If the value of the function increases as x increases, then this is known as exponential growth. If the value of the function decreases as x increases, then this exponential decay.

Example 1

Draw the graph of y= 2 x 3^x for -4 ≤ x ≤ 4.

 x -4 -3 -2 -1 0 1 2 3 4 0.5xx2^x 0.03 0.06 0.1 0.2 0.5 1 2 4 8
