Answer 1

`0\leq x \leq12`, where,
`x\geq 0`

Explanation:

Domain of a graph is the set of all possible values of
`x`. It is the independent variable and is plotted along the
`x` axis.

From the graph,

The number of cars washed is along the
`x` axis. So, the domain includes the possible values for the number of cars washed.

The starting value of the graph is at point (0,-20) and the end point is (12,40)

So, the possible values of x varies from 0 to 12.

Therefore, the domain of the graph is:

`0\leq x \leq12`, where,
`x\geq 0`
