The function f(x) = 1.1x-3x + 270x + 551 below models the number of discharges from the military, f(x), of active-duty gay service members under the "don't ask, don't tell" policy x years after 1994. Complete parts a and b. Number of Discharges 1400- 900- 400+ 0 (4,f(4)) (0,f(0)) 5 Years after 1994 10 Ly ---- a. Find the slope of the secant line from = 0 to x2 = 4. The slope of the secant line is (Round to the nearest whole number as needed.)
