Continuation of the question:

Which answer choice best describes the domain and range of the function for this situation?

A

• Domain: All real numbers greater than or equal to 0 and less than or equal to 100
• Range: All real numbers greater than or equal to 0 and less than or equal to 50

B

• Domain: (-2)
• Range: (100)

C

• 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

D

• Domain: (100)
• Range: (-2)

------------

As per the graph, the domain is x-values in the interval [0, 50] minutes and the range is y-values in the interval [0, 100] percentage.

Correct answer choice is therefore:

• Option C

The rest are all incorrect
