Intro to Graphing Exponentials Mon Oct 22 nd / Tue Oct 23 rd

Remember Exponent Rules…

Vocabulary Exponential Function – has the form y = ab x, where a ≠ 0 and the base b is a positive number other than 1. If a > 0 and b > 1, then the function y = ab x is an Exponential Growth Function, and b is called the Growth Factor Exponential Decay Function – has the form y = ab x, where a > 0 and 0 < b < 1 (this means b is a fraction)

Graphing y = ab x-h +k h – moves graph left and right (opposite) k – moves graph up and down
