I need to find the domain and range for both graphs and I don’t know what to do, could I get help please ?

Given:
The graph of two linear relationships is given.
Required:
We have to find the domain and range of both the relationships.
Explanation:
Domain: The domain of a function is defined as the values of the variable for which the function is defined and for these values the function gives a finite value.
Range: The range of a function is defined as the values which the function gives when we put some value from the domain of that function.
For the first relationship:
We can see that the graph of the relationship is drawn from 0 to 18 and for these values, the function gives the value between 200 to 2000.
Hence its domain and range are
[tex][0,18]\text{ and }[200,2000][/tex]respectively.
For the second relationship:
We can see that the graph of the relationship is drawn from 0 to 4 and for these values, the function gives the value between 0 to 160.
Hence its domain and gange are
[tex][0,4]\text{ and }[0,160][/tex]respectively.
Final answer:
Hence the final answer is:
For the first relationship
[tex]\begin{gathered} Domain:[0,18] \\ Range:[200,2000] \end{gathered}[/tex]For the second relationship
[tex]\begin{gathered} Domain:[0,4] \\ Range:[0,160] \end{gathered}[/tex]
