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 ground is f(x) =-32xz + vx + d. In this function, x is time, v is the initial (vertical) velocity in feet per second, and d is the initial distance above the ground in feet. If vis positive, then the initial velocity is upward. If vis negative, the initial velocity is downward. Part A Write the function if Cecily releases the ball 40 feet above the ground at a velocity of 32 feet per second, and then graph it by going to your math tools and opening the Graph tool. To create the graph, select the correct relationship and then enter the values for the variables. Capture a screenshot of your graph and paste it below. BIUXX , 15px AVLy BVB The velocity is 32 feet per second. She throws/releases the ball 40 feet above the ground. So the function will be, f(d)=-32d2+32d+40. 40 20 Characters used: 136 / 15000Part B What does the maximum represent, and what is it? BIYXX , 15px BVB Maximum represents the vertex and its cordinate is (0.5,48). Characters used: 60 / 15000 Part C What does the y-intercept represent, and what is it? B I Y XX, 15px BVBV Y-Intercept represents 40 units. Characters used: 32 / 15000 Part D What do the x-intercepts represent, and what are they? Are they both useful? B IY XX , 15px BVB The *-Intercepts represents represent the point at which the ball reaches the ground height. The x-Intercepts are (-0.725,0) and (1.725,0). Only one of them is useful.
