The function f ( x ) = 1.1 x 3 − 35 x 2 + 264 x + 557 models the number of discharges, f(x), under "don't ask, don't tell” x years after 1994. Use this model and its graph, shown below, to solve Exercises 29-30. a. Find the slope of the secant line, rounded to the nearest whole number, from x 1 = 0 to x 2 = 4 . b. Does the slope from part (a) understimate or overestimate the average yearly increase that you determined in exercise 27? By how much?
