A student worked out at a $ \mathbf{g y m} $ continuously for $ \mathbf{5 0} $ minutes. The graph shows the remaining percentage of the workout as a linear function of $ x $, the time in minutes.

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\} $
