[tex]\bf (\stackrel{\downarrow }{-4},-2), (\stackrel{\downarrow }{0},-3), (\stackrel{\downarrow }{2},7), (\stackrel{\downarrow }{1},4)\qquad \qquad \stackrel{\mathbb{DOMAIN}}{\{-4,0,2, 1\}}[/tex]
recall, the x-coordinates are always the domain, and the y-coordinates are the range.
Step-by-step explanation: To find the domain in a set of ordered pairs, we simply need to order the x-values or inputs from least to greatest.
In our list of ordered pairs, are x-values are as followed.
-4, 0, 2, 1
Now, let's arrange these from least to greatest.
-4, 0, 1, 2
Domain ⇒ -4, 0, 1, 2
