    Answer:  x-intercept

    Step-by-step explanation:

    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.
