Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
y =
64(0.97)x

Hello there!

Using the given exponential function of y = 64(0.97)^x, we can tell that it is a decaying exponential function since the rate is less than 1.

The percent of decrease is 3% since 97% of the value is retained per x time.
