Exponential growth - Identify the percent rate of change.

Question

Determine whether the function represents exponential growth or exponential decay

f(t)=6(0.4)^t-3

Identify the percent rate of change.

The rate of change is %

Answer 1

this equation represents an exponential decay of 60% . The general decay equation is A=P(1-r)^t

^{A=6(1-.6)^(t-3). If t is time than t must be greater than or equal to 3.}
