The ordered pairs are:
• A = (-4, -5)
,
• B = (-2, -1)
,
• C = (1, 2)
,
• D = (3, -1)
,
• E = (-2, 3)
In an ordered pair the x-coordinate always is written on the left and the y-coordinate on the right.
The domain is all the x values:
Domain: {-4, -2, 1, 3, -2}
The range is all the y-values:
Range: {-5, -1, 2, -1, 3}
This relation is not a function, because there are repeated values of x in the domain. For a relation to be a function there cant' be more than one value of x for different values of y
