problem solving for a test tomorrow!!!
A company first started recording their profit making in december 2007, before the financial crisis. They recorded it quarterly for 2 years. It is recorded in 1000's dollars.
P(t) = t^2-9t+14
(x intercepts: 2 and 7)
(y intercept: 14)
(vertex: 4.5, -6.25)
1) When the company recorded its lowest profit, what quarter did this happen in?
2) when did there profit first start to rise?
3) Find P(t) when t=0
4) When did the profit reach 20 000 dollars?
5)calculate k if the company made no loss.
P(t) = t^2-9t+14+k
