Find the area under the curve y = 17 x2 and above the xaxis. Round your answer to three decimal places. Area = a (a) Use the figure to find the value of f (x) dac. 3 y 1 f (ac) -3 -2 -1 2 f (x) dac = -3 (b) If the area of the shaded region is A, what is / f(x) da? -3 f(x) da = 3A car comes to a stop six seconds after the driver applies the brakes. While the brakes are on, the following velocities are recorded. Timesincebrakesapplied(sec) 0 2 4 6 Velocity(ft/sec) 80 46 14 0 Give lower and upper estimates for the distance the car traveled after the brakes were applied. A lower estimate on the distance traveled is l feet. An upper estimate on the distance traveled is n feet
