1. Ch 8: Exponents F) Graphing Exponential Functions Objective: To graph exponential functions

2. Exponential Function An equation in the form: y = bg x Definitions Rules Note: The direction of the graph should be as follows: 1) Plug in values for “x” (-2, -1, 0, 1, 2, 3, 4) and solve for “y” g > 10 < g < 1 updown 2) Plot the points and draw a curve through them.

3. Graph Example 1

4. Graph b = 10 g = 0.8 decreasing y-int. Example 2

5. Graph b = 5 g = 1.2 increasing y-int. Example 3

6. Graph b = 50 g = 0.6 decreasing 160 140 120 100 80 60 40 20 -3 -2 -1 0 1 2 3 4 5 6 7 8 Example 4
