A movie company earns revenue from royalties and movie sales. From 2009 to 2014, the revenue (in millions of dollars) from royalties r and movie
sales s can be modeled by the equations
r (t) = -0.4t3+ 2.3t² – 3.1t + 4.2
s (t) = 3.8t2 – 2.8t + 2.1,
where t is the number of years since 2009.
a. Find (r +s) (t).
