Question

Mr. Patton'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 equation \( f(8) = 0 \) indicates that at \( x = 8 \) seconds after the rocket was launched, the height of the rocket, \( f(x) \), is 0 feet. This means the rocket has returned to the ground (or the same elevation as the launch point) 8 seconds after launch. In practical terms, this typically suggests that the rocket has finished its flight and has landed.
