The price of an item is initially $900. For the first 3 years the price increases by $20 each year. For the next 6 years the price decreases by $30 per year. From then on the price increases by $35 per year. Find a piecewise-defined function P that specifies the price of the item after t years have passed. Let P(t) = the price of the item in dollars after t years have passed.
(a) When 0 < t 3, the value of P(t) is given by what part of the piece-wise-defined function?
(b) When 3 < t 9 the value of P(t) is given by what part of the piecewise-defined function?
(c) When t > 9 the value of P(t) is given by what part of the piecewise-defined function?
