Question

Use the graph of the function to find its domain and range. In interval notation.

Answer 1

Recall that the domain of a graph is all the values of the graph from left to right and the range is all the values of the graph from down to up.

From the given graph we get that the domain is the red set and the range is the blue set.

The red set in interval notation is:

`[-7,-2].`

The blue set in interval notation is:

`[-4,7].`

Answer:

`\begin{gathered} Domain=[-7,-2], \\ Range=[-4,7]. \end{gathered}`
