Answer by tutorcecilia(2152)   (Show Source):
You can put this solution on YOUR website! R is not a function because points (1, 2) and (1, 0) both have the same value for x. Therefore, the x's and y's do not have a one-to-one relationship.
.
b) Point (0,-4) lies on the y-axis.
.
c) (-3, 4)
.
d)
x: 1 , -3 , 0 , 1
.
y: 2 , 4 , -4 , 0)
