A store noticed that it could model its yearly profit by the function p ( t ) = 0.3 t 2 + 4.8 t − 9, where p is measured in thousands of dollars and t is measured in years. (A) Find the profit (or loss) of the store in the 1st year. (B) Use the function given in part A to estimate the number of years needed for the store to break even (that is, when is the profit zero.)
