Derivatives and Rates of Change

After t years, the value of a car purchased for V(t) = 20,000(3/4)^t

(a) use a graphing utility to graph the function and determine the value of the car 2 years after it was purchased.

(b) Find the rates of change of V with respect to t when t = 1 and t - 4.

(c) free hand stetch graph of V'(t) and determine the horizontal asymptote of V'(t). Interpret its meaning in the context of the problem.
