One of the ideas that you have explored in previous courses is how to describe a set of data. One of the ways that you may have seen before is finding an average (also called a mean). Read the Math Notes box for this lesson to review what a mean is and how to find it. Then find the mean for each set of data below.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
