The height of the ball y (in yards), x seconds after being launched is given by: Equation A: Equation B: Equation C: y =-2x2 + 8x + 10 y =-2(x + 1 1 (x-5) y = -2(x - 212+18 1) State the form of each equation. A: B: C: 2) Make a graph that models the ball. Be sure to plot the critical points so that your graph is accurate and label your axes appropriately @ Write these critical points here! Then, darken the "real world" portion of your graph. 3) Answer the following questions. Explain HOW you got your answer...be very specific! (a) How high was the ball when it was launched?
