4) An operations VP has developed an efficiency-rating system for the various departments of her organization. The efficiency-rating is modeled by the following polynomial function. E(x) = 0.5x3 -3x2 4 5x, where x is the number of new employees hired in a department, and E(x) is the efficiency rating based upon the model. A) Based upon the following graph of E(x) = 0.5x3 -3x3 +5x, what is the right-end behavior and the left-end behavior for this polynomial function written with infinity notation? 1. right-end behavior: 2. left-end behavior: TE( x) Ex- 0.5x - 3x + 5.X 12 13- MacBook Air
