interval before the ball hits the ground.
initial height = 0; hits the ground between 5 and 6
seconds
o initial height = 150; hits the ground between 5 and 6
seconds
initial height = 0; hits the ground between 3 and 4
seconds
initial height = 150; hits the ground between 4 and 5
seconds

step-by-step explanation:

hoped i lol

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
