Question

identify the initial amount a and the growth factor b in each exponential function.
f(t)=1.5^t

Answer 1

Initial amount is outcome of formula if t=0.

Growth factor: factor by which the amount is multiplied every time t is incremented 1, so:
b=f(t+1)/f(t),

e.g. b=f(2)/f(1).

Once you've found b in this way, you'll notice somthing...
