CityU Polynomial Adrenaline Flowing in the Veins Algebra Help

The polynomial model P = −0.02n2 + 22n + 22 is used by coaches to get athletes fired up so they can perform well. The polynomial represents the performance level related to various levels of enthusiasm, from n = 1 (almost no enthusiasm) to n = 100 (maximum level of enthusiasm). In your initial posting, evaluate this polynomial model for each of the following values: n = 20, n = 40, n = 60, and n = 80, and post your results (include your calculations as an attachment). Describe what happens to performance as we get more and more fired up, and explain why you think this happens. Share an example of a time when you (or someone you know) was too enthused and thus did poorly at something you/they were expecting to do well.
