Question

Given H = f(t) where H is the height in meters of an object and t is the time in seconds since it was launched, which of the following is the best interpretation of f(8) = 12?

Answer 1

Answer:

Recall that the height of the object, in meters, is a function of elapsed time, in seconds. Thus what $f(8)=12$ means is that the object is at a height of 8 meters when 12 seconds have passed since its launch.
