Answer: x-intercept
<u>Step-by-step explanation:</u>
NOTES
1) Parabolic motion is represented by the equation:
h(t) = -9.8t² + vt + h (in meters per second²), v is velocity
or
h(t) = -32t² + vt + h (in feet per second²), v is velocity
2) The x-axis is time (in seconds) & the y-axis is height (in meters or feet).
Since you want to know what time the object hit the ground, h = 0
Therefore, you are looking for the zero of the equation, which is on the x-axis, thus is the x-intercept.
