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.
