Answer:
h ≥ 0 is the domain.
Step-by-step explanation:
The plumber charges $110 per hour.
If h represents the number of hours that he works, then the equation of his earning will be a function h and given by
E = 110h ...... (1)
Here, h is the independent variable and E is the dependent variable.
So, the domain of this function means the possible values of h.
Now, it is evident that h ≥ 0 and h can not be negative.
So, the domain value of h ≥ 0 is relevant to the graph that shows his earning. (Answer)
