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 number greater than ar equal to 0 and less than or equal to 30
all real number greater than ar equal to 0 and less than or equal to100
{0,100}
{0,30}
The domain of this situation is all real numbers greater than or equal to 0 and less than or equal to 30.
In this context, the domain represents the possible values for time in minutes. The student worked out continuously for 30 minutes, so time cannot be negative or greater than 30. Therefore, the correct answer choice is "all real numbers greater than or equal to 0 and less than or equal to 30."
