A student worked out at a gym
continuously for 30 minutes. The
graph shows the remaining
percentage of the workout as a
function of time in minutes. Which
answer choice describes the domain
of this situation?
All real numbers greater than or equal
to 0 and less than or equal to 30
All real numbers greater than or equal
to 0 and less than or equal to 100
{0, 100}

The domain of this situation is all real numbers greater than or equal to 0 and less than or equal to 30. This is because the student worked out continuously for 30 minutes, so the graph only includes values between 0 and 30 on the x-axis.
So what is the answer
The answer is "All real numbers greater than or equal to 0 and less than or equal to 30".
