Determine whether the function represents exponential growth or exponential decay

Question

Determine whether the function represents exponential growth or exponential decay

f(t)=2(2.3)^2t

Identify the percent rate of change.

The rate of change is %

Answer 1

this equation represents exponential growth. The general equation is A=P(1+r)^t. In this case, rate of growth is 130% (1.3) and since the exponent is 2t, the rate of growth changes every two years.
