Exponential Graphs and Models
Exponential Functions have the form: y = a * b^x, y = a (b)^x.
Where a is the start/initial amount, b is the growth/decay factor, and x is the number of growths or decays.
Exponential Functions are used when the function outputs are multiplied by the same amount.
How to graph: the y-intercept is the first value. For the next value (x=1) multiply the y-int by the growth factor.
