Question

Rohan is at an amusement park. While waiting in line, he reads the statistics on the roller coaster he is about to board. The coaster reaches a maximum speed of 75 miles per hour, and the ride lasts three minutes. Identify the domain and range using words and inequalities.

Answer 1

We know that the ride that Rohan wants to take lasts for 3 minutes, and goes up to maximum speed of 75 miles per hour

We have to find the domain and range

Domain: all possible values of the independent variable

Range: all possible values of the dependent variable

In this situation, the independent variable is time and the dependent variable is speed

Hence,

Domain = [0,3] minutes

Range = [0,75] miles per hour
