Graphing Exponential Functions

The general form of an exponential function is y = a n, where a is a positive number.

Example:

Draw the graph of y = 3^x for –1 ≤ x ≤ 2.

Solution:

y = 3^x

From the graph above, we notice the following properties of the exponential curve:

a) As the value of x increases, the value of y increases far more than the increase of value of x.

b) All the values of y are positive.

c) The curve never crosses the x-axis.
