Identify if the exponential function is growth or decay. f(x) = 3 x (0.8)^x-5

A) Decay. The growth factor 0.8 is between 0 and 1, so the equation is exponential decay.

B) Growth. The growth factor 0.8 is between 0 and 1, so the equation is exponential growth.

C) Decay. The growth factor 3 is bigger than 1, so the equation is exponential decay.

D) Growth. The growth factor 3 is bigger than 1, so the equation is exponential growth.
