If a population doubles every year, what is the growth factor?

Back

The growth factor for a population that doubles every year is 2.

What does a decay factor of 0.7 represent?

Back

A decay factor of 0.7 means that the quantity decreases to 70% of its previous value each time period.

What is the significance of the base in an exponential function?

Back

The base in an exponential function determines the rate of growth or decay. A base greater than 1 indicates growth, while a base between 0 and 1 indicates decay.

How can you identify exponential growth or decay from a graph?

Back

Exponential growth is represented by a curve that rises steeply, while exponential decay is represented by a curve that falls steeply.
