Question

HELP ASAP! A plumber charges $110 per hour. If h represents the number of hours that he works, which domain values are relevant on a graph that shows his earnings?

A) h ≥ 0
B) h ≥ 1
C) h ≥ 110
D) all real numbers

Answer 1

First you need to figure out how many hours he has been working for you, lets say h = 1 then you answer would be both A and B, if it is h = 2 then your answer is C, B, A, and maybe D (Because I am not really sure what D means)

Answer 2

The answer is A) h ≥ 0

Explanation:

h ≥ 0

The equation of his earnings is $110h. He can't work negative hours.
