Question

Mr. Wagner's physics class went to the football field to launch a rocket into the air. The rocket's height in feet, f(x), depends on the number of seconds, x, that have elapsed since launch. What does f(8)=0 tell you?

Answer 1

The notation \( f(8) = 0 \) means that at \( x = 8 \) seconds after the rocket is launched, the height of the rocket is 0 feet. In practical terms, this indicates that the rocket has returned to the ground after being launched. Specifically, it could imply that the rocket has completed its flight path and has either landed back on the football field or was in the process of descending after reaching its peak height.
