Question

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

Answer 1

Given:

The graph of two linear relationships is given.

Required:

We have to find the domain and range of both the relationships.

Step-by-step 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

`[0,18]\text{ and }[200,2000]`

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

`[0,4]\text{ and }[0,160]`

respectively.

Final answer:

Hence the final answer is:

For the first relationship

`\begin{gathered} Domain:[0,18] \\ Range:[200,2000] \end{gathered}`

For the second relationship

`\begin{gathered} Domain:[0,4] \\ Range:[0,160] \end{gathered}`
