Answer:

A root of the quadratic or an x-intercept.

Step-by-step explanation:

When the rocket hits the ground at (8, 0), we can see that it took 8 seconds to reach 0 height.

This can mean multiple things.

1. It tells us one of the x-intercepts of the graph.

2. It tells us a root of the quadratic function.

Answer:

the points are called the x intercepts, the zeros of the function, or the roots of the equation.

Step-by-step explanation:

When the parabola crosses the x axis, the points are called the x intercepts, the zeros of the function, or the roots of the equation.  In this case it is the point where the rocket hits the ground.
