Please help me I don’t get this?

Step-by-step explanation:

ok so the domain is the 1st number in a set of coordinates and the range is the 2nd number in a set of coordinates. the domains are (-1,1,2,4) and the ranges are (-2,1,3,-2). this is a function because each domain has exactly one range.

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
