Question

What is the domain and range of (-4,0) (-1,-3) (1,0) (3,-2) (4,0)

Answer 1

Domain: {-4, -1, 1, 3, 4}
Range: {-3, -2, 0}

Answer 2

`\begin{gathered} D=(-4,4) \\ R=\lbrack-3,0\rbrack \end{gathered}`

Step-by-step explanation

The domain is the set of all input values of a function while the range is the set of all output values of a function.

Therefore, from the graph, the domain is:

`(-4,4)`

Note: An open bracket is used since the graph does not take the x-values -4 and 4.

The range is:

`\lbrack-3,0\rbrack`
