a. Find an equation that models the height of the ball t seconds after it is thrown.
b. What is the maximum height the baseball will reach? How many seconds will it take to reach that height?
8. Find the zeros of the function algebraically. f(x) = x2 + 2x – 8
9. Find the zeros of the function algebraically. f(x) = x2 + 2x + 8
10. Find the zeros of the function algebraically. f(x) = 2x2 – 10x + 3
