Q. Dakota is about to ride the fastest roller coaster in the world. The function f(x)f(x) gives the speed of the roller coaster in miles per hour xx seconds after the ride starts.\newlineWhat does f(25)>123f(25) > 123 tell you?\newlineChoices:\newline(A)The roller coaster is moving faster than 2525 miles per hour 123123 seconds after the ride starts.\newline(B)The roller coaster is moving faster than 123123 miles per hour 2525 seconds after the ride starts.
  1. Understand function and variable: Understand the function f(x)f(x) and the variable xx. The function f(x)f(x) represents the speed of the roller coaster in miles per hour at xx seconds after the ride starts. The variable xx represents the number of seconds after the ride starts.
  2. Interpret inequality: Interpret the inequality f(25)>123f(25) > 123.\newlineThe inequality tells us that the speed of the roller coaster is greater than 123123 miles per hour at 2525 seconds after the ride starts.
  3. Match correct interpretation: Match the correct interpretation with the given choices.\newlineThe correct interpretation of f(25)>123f(25) > 123 is that the roller coaster is moving faster than 123123 miles per hour 2525 seconds after the ride starts. This matches choice (B).
