Question

Can someone help me with this I’m very confused?

Answer 1

{-5, 0, 1, 5}

The domain is just the x from the coordinates (x,y)

Answer 2

(-5, 0, 1, 5)

Explanation:

It is asking for all the points on the domain (the x line / the one going sideways)

So you take each point and bring it down until it touches the x line. Then you order the numbers you get from least to greatest.
