Question

In P.E. class, Darrell gets to climb ropes! His height above the ground after x seconds of climbing is given by the function f(x). The height is measured in feet.
What does f(12)=25 tell you?

Answer 1

The notation f(12) = 25 indicates that after 12 seconds of climbing, Darrell is 25 feet above the ground. In other words, at the time t = 12 seconds, Darrell's height has reached 25 feet. This provides a specific measurement of his altitude at that particular moment during his climbing activity.
