How do you identify an exponential function from a table of values?

Back

To identify an exponential function from a table, look for a constant ratio between consecutive outputs when the inputs are equally spaced.

What does the base of an exponential function represent?

Back

The base of an exponential function indicates the growth (if > 1) or decay (if < 1) rate of the function.

How do you find the equation of an exponential function from a set of points?

Back

To find the equation, use the points to determine the initial value and the base by solving the equations formed by the points.
