Question

a student worked out at the gym continuously for 50 minutes. The graph shows the remaining percentage of the workout f(x) as a linear function of x, the time in minutes

Answer 1

Domain: All real numbers greater than or equal to 0 and less than or equal to 50

Range: All real numbers greater than or equal to 0 and less than or equal to 100

Explanation

The workout is at 100% at 50 mins. Anything less would be under these two numbers. Since the percentage of workout is on the y-axis, anything between zero and 100 can be possible. The time is on the x-axis, so anything 0 to 50 can be possible.
