Show all calculations and interpret the result in the context of the problem. (Assessing Communication and interpretation) 2. Explain how you may use the graph to estimate the total Revenue from 2007 to 2013. What assumptions are you making, is the estimate an over estimation or under estimation? Explain. Extra points for calculating the estimate. (Assessing Assumptions/Application/Analysis) 3. Suppose the Revenue function R is modeled by the equation: R(t) = -0.5972t3 +51. 187t2 - 485. 54t+ 2199.0 Formulate and obtain the total Revenue from 2007 to 2013 using the Revenue function R(t) in part 2.
