The annual cost C (in thousands of dollars) and revenue R (in thousands of dollars) for a company each year from 2010 through 2016 can be approximated by the models
C = 254 − 9t + 1.1t2 and R = 341 + 3.2t
where t is the year, with t = 10 corresponding to 2010.
(a) Write a function P that represents the annual profit of the company.
(b) Use a graphing utility to graph C, R, and P in the same viewing window.
