Document Summary
Instructions: the following 10 questions are worth 10 points each. Write your answers on separate answer sheets, not on this paper. (1) sketch the graph of v = v0(1 e t) where t is time, v0 is a positive constant and v is the speed of a falling raindrop. What does v0 represent? (2) a radioactive substance decays exponentially. If yes, solve for the inverse function y = f 1(x) and sketch its graph. (6) find the inverse function to f (x) = 1 + e x . (7) sketch the graphs: (a) f (x) = 4 cos 2x (b) f (x) = e x sin x (8) f (x) =
