Directions and Analysis Task 1: Throwing a Ball
Cecily is on her roof and wants to throw a ball straight up in the air and figure out how
long it will take to reach the ground. The function that models an object falling to the
þround is f(x) = -32x2 + VX + d. In this function, x is time, vis the initial (vertical) velocity
in feet per second, and d is the initial distance above the ground in feet. If v is positive,
then the initial velocity is upward. If v is negative, the initial velocity is downward.
a. Write the function if Cecily releases the ball 40 feet above the ground at a
velocity of 64 feet per second, and then graph it using the Edmentum Graphing Tool.
Capture a screenshot of your graph and paste it below.
