Given two revenue models (in millions of dollars) for a large corporation, where both models are estimates of revenues from 2015 through 2040 and $t = 0$ corresponds to the beginning of 2015. $R = 6.11 + 0.33t + 0.06t^2$ $R = 6.11 + 0.16t + 0.01t^2$ Hints: Sketch a graph of the 2 functions, also think about the definition of time carefully along with the time period asked for below. Which model predicts the greater revenue? $R = 6.11 + 0.33t + 0.06t^2$ $R = 6.11 + 0.16t + 0.01t^2$ How much more revenue does that greater revenue model predict over the 6 year period from 2021 through 2026? (Round your answer to three decimal places.) 7.920 millions of dollars
