Question

The speed of a hockey puck x seconds after a hockey stick strikes it is given by the function f(x). The speed is measured in feet per second.
What does f(0.5)=150 tell you?

Answer 1

The expression \( f(0.5) = 150 \) indicates that the speed of the hockey puck, half a second (0.5 seconds) after being struck by the hockey stick, is 150 feet per second. This means that at that specific moment in time (0.5 seconds after the strike), the puck was traveling at a speed of 150 feet per second.
