To determine how long the ball is in the air, he would need to calculate the x-intercepts
How to interpret the function?
The function of the height of the ball is given as:
h(t) = 32t - 16t^2
When the ball is on the floor, we have:
h(t) = 0
This means that
32t - 16t^2= 0
The values of t when h(t) = 0 are the initial and the final time the ball spent in the air
Hence, to determine how long the ball is in the air, he would need to calculate the x-intercepts
