## anonymous one year ago Need help Derrick made a goal for 2 points during the basketball game. The path of the ball's height in feet can be modeled by y=-x^2-2x+24 Use a graph of the function to determine the maximum height of the ball. https://media.education2020.com/evresources/2003-18-02-00-00_files/i0260001.jpg A. The maximum height of the ball is 20 feet. B. The maximum height of the ball is 30 feet. C. The maximum height of the ball is 25 feet. D. The maximum height of the ball is 24 feet.

HI!!

max is what you get at the vertex first coordinate of the vertex is $-\frac{b}{2a}=-\frac{-2}{2\times (-1)}=-1$

4. misty1212

you are right, it is C 25
