Henri puts aside $10 cash every month in a shoebox. He also makes a one-time deposit of $1,500 in a savings account at 9% annual interest, compounded yearly.

Amount of shoebox savings: f(t) = 120t

Amount of savings account: g(t) = 1,500(1.09)t

Which function represents the amount of money Henri will have after t years?

(f + g)(t) = 1,500(1.09)t + 120t, t ≥ 0
(f + g)(t) = 1,500 + 120t (1.09)t, t ≥ 0
(f ∙ g)(t) = 1,500(130.8t)t, t ≥ 0
(f ∙ g)(t) = 1,500(121.09t)t, t ≥ 0

Which graph has a rate of change of zero
