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.
