The cost of the item is initially $900. For first 2 years price rises by $35 each year. For next six years price reduces by $30 per year. From then on price increases by $30 per year. Determine the piecewise-defined function P which specifies price of item after t years have passed. ConsiderP(t) = price of item in dollars after t years have passed.
1. When 0 < t 2, value of P(t) is given by what part of piecewise-defined function?
2. When 2 < t 8 value of P(t) is given by what part of piecewise-defined function?
3. When t > 8 value of P(t) is given by what part of piecewise-defined function?
