Graphing Exponential Functions

 

An equation in the form y = ax where a > 0 and a ≠ 1 is called an exponential function. You can use a calculator to evaluate exponential functions.

Example: Use a calculator to approximate 0.5-3.5 + 2 to the nearest hundredth.

You can use values of exponential expressions to find ordered pairs that satisfy exponential functions. Then you can use the ordered pairs to graph the function.

Prepare a chart of ordered pairs and then graph each of the following functions.

1. y = 0.3x

2. y = 3x + 1

3. y = 32x-1

4. y = (½)x - 2
