Activity : Investigating Exponential Functions * Below are 3 functions. Sketch the graph of each function. 1.) f ( x ) = 2x 2 . ) 9 ( x ) = 3 * 3. ) h(x ) = 4x * Compare the graphs . Answer the following questions. 1.) Are all the given functions exponential functions? How do you know? 2.) What are the similarities of the graph of functions? What are the differences? SIMILARITIES : DIFFERENCES
