A football is kicked into the air. The height of the football can be modeled by the equation h = -16x^2 + 16x, where h is the height reached by the ball after x seconds. When does the
ball touch the ground?

x = 0 and x = 1

Step-by-step explanation:

Given that,

A football is kicked into the air. The height of the football can be modeled by the equation :

Where

h is the height reached by the ball after x seconds

When it touches the ground, h = 0

So,

So, it will touch the ground at x = 0 and x = 1 seconds.

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4
