Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.

y = 7900 (1.05)

What is the growth increase

Y = 16 (0.25) ^x

The exponential equation represents an exponential decay because the rate of decay is 0.25 which is less than 1.

The general form equation is:

y (x) = a (1-r) ^x such that r is the decay percent.
