. If the y-intercept of f(x) = a(x 3)(x + 2) is 3, find a. . A ball is thrown upward from the top of a 96 foot high tower with an initial velocity of 80 ft/Sec. Afte how many seconds does the ball reach its maximum height and how high is it at that time? (Use your calculator to calculate the maximum given that h(t) = -16t2 + vot + ho; v0 = initial velocity, ho initial height, t = time, and h = height) . Given the information in #11, after how many seconds will the ball hit the ground? \"NOTE: you must show your equation for #11 and 12. Label your answers and provide units
