May someone, please help me with this
At Speedy Car Wash, it cost $8.00 for an outside wash and $0.89 for each minute spent detailing the inside. The function, f(m)=8+0.89m, where f(m) represents the cost of the car wash and m represents the minutes they spend detailing the inside of your car.
What is a realistic domain for this function?
a. all real numbers
b. m is greater than 0
c. m is less than or equal to 0
d. m is greater than or equal to 0
