Question

Give the domain and range.

Answer 1

c. domain: {-2, 0, 2}, range: {-1, 1, 3}

Explanation:

Given:

There are three points on the graph.

Locate the
`x` and
`y` values of the points on the graph.

The points are
`(-2,-1),(0,1),\textrm{ and }(2,3)`

Domain is the set of all possible
`x` values. Here, the
`x` values are -2, 0 and 2.

So, domain is: {-2, 0, 2}.

Range is set of all possible
`y` values. Here, the
`y` values are -1, 1 and 3.

So, range is: {-1, 1, 3}
