Chapter 3 Lesson G

2
**Exponential Functions**

The general exponential function has form f(x) = a^x where a>0, a≠1 y=0 is a horizontal asymptote

3
Example Graph y= 2^x

4
**General Exponential Function**

y= a x b ^(x-c) +d b controls how steeply the graph increases or decreases c controls horizontal translation D controls vertical translation and y=d is the equation of the horizontal asymptote

5
**General Exponential Function**

If a>0, b>1 If a>0, 0<b<1 If a<0, b>1 If a<0, 0<b<1

6
**Horizontal Asymptotes**

y= a x b ^(x-c) +d In this function y=d is the horizontal asymptote Using these you can obtain a reasonably accurate sketch of the graph Horizontal asymptote Y-intercept Two other points, say when x=2, x=-2
