The quarterback, Wussel Rillson, tossed a football down the field according to a parabolic path that followed the function d(x) = -4x² + 26x + 5, with d(x) = the height in feet above the ground and x the time in seconds. Assuming no one touched the ball, how many seconds after releasing the ball does it take for the ball to reach the ground?
