Question

Marie is about to ride the fastest roller coaster in the world. The function f(x) gives the speed of the roller coaster in miles per hour x seconds after the ride starts.
What does f(25)>123 tell you?

Answer 1

The inequality \( f(25) > 123 \) indicates that the speed of the roller coaster, \( f(x) \), 25 seconds after the ride starts is greater than 123 miles per hour. This means that at 25 seconds into the ride, the roller coaster is traveling faster than 123 mph. In the context of the ride, it suggests that the experience of riding the roller coaster at that moment is very thrilling, as it exceeds a significant speed threshold.
