Q. In P.E. class, Jeffrey gets to climb ropes! His height above the ground after xx seconds of climbing is given by the function f(x)f(x). The height is measured in feet.\newlineWhat does f(12)=25f(12) = 25 tell you?\newlineChoices:\newline(A)Jeffrey climbed to a height of 1212 feet in 2525 seconds.\newline(B)Jeffrey climbed to a height of 2525 feet in 1212 seconds.
  1. Given Function Interpretation: We are given the function f(x)f(x) which represents Jeffrey's height above the ground in feet after xx seconds of climbing. We need to interpret what f(12)=25f(12) = 25 means in this context.
  2. Function Definition: The function f(x)f(x) is defined such that xx represents the time in seconds, and f(x)f(x) represents the height in feet. Therefore, f(12)=25f(12) = 25 means that after 1212 seconds, Jeffrey has reached a height of 2525 feet.
  3. Correct Interpretation Choice: Now we need to choose the correct interpretation of f(12)=25f(12) = 25 from the given choices. Choice (A) suggests that Jeffrey climbed to a height of 1212 feet in 2525 seconds, while choice (B) suggests that Jeffrey climbed to a height of 2525 feet in 1212 seconds. Based on our understanding of the function f(x)f(x), choice (B) is the correct interpretation.
