Ruth 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.

Question

What does f(25)>123 tell you?

Answer 1

The inequality \( f(25) > 123 \) tells us that 25 seconds after the ride starts, the speed of the roller coaster exceeds 123 miles per hour. This means that at 25 seconds into the ride, the roller coaster is traveling faster than 123 miles per hour.
