There's a typo. It should read
h = -16t^2 + 28t + 8
A. No. The ball starts at a height of 8 ft, so the negative x-intercept occurs before it was hit.
B. Just solve for t when h = 0
The height h (in feet) of a fly ball in a baseball game can be modeled by h=-16^2+28+8, where t is time.
A. Do both t-intercepts of the graph of the function have meaning in this situation? Explain?
B. No one caught the fly ball. After how many seconds did the ball hit the ground?
