PLZ HELP ME I'M DESPERATE. 1 QUESTION. I NEED 100% :C

Jane threw a basketball up in the air. The following table represents the height f(t), in meters, of the ball above the ground at time t seconds:

Time (t)
(in seconds) Height f(t)
(in meters)
2 10
4 15
6 10
8 0

Which of the following is represented by the x-intercept of f(t)? (1 point)


The ball reaches the maximum height in 4 seconds.

The ball reaches a maximum height of 15 meters.

The ball was thrown from a height of 10 meters.

The ball touches the ground after 8 seconds.

Respuesta :

x intercept is where y=0
y=height=f(t)
so where it equals 0 is at t=8
that means where the ball touches the ground

it touches the ground after 8 seconds is what it means

Answer: it touches the ground after 8 seconds
