Front

What does the base 'b' in an exponential function represent?

Back

The base 'b' represents the growth (if b > 1) or decay (if 0 < b < 1) rate of the function.

Front

What is exponential growth?

Back

Exponential growth occurs when a quantity increases by a consistent percentage over a period of time, resulting in a rapid increase.

Front

What is exponential decay?

Back

Exponential decay occurs when a quantity decreases by a consistent percentage over a period of time, resulting in a rapid decrease.

Front

How do you identify exponential decay on a graph?

What does it mean if an exponential function has a base greater than 1?

Back

If the base is greater than 1, the function represents exponential growth.
