which of the following ordered pair could not be included in this set if it is a function? { (-4, 2), (3, 6), (4, 3), (x, y) }

a) (x, y) = (4, -3)

b) (x, y) = (3, 6)

c) (x, y) = (1, 2)

d) (x, y) = (-3, 6)

Option A) (x, y) = (4, -3)

Step-by-step explanation:

we know that

A function is a relation from a set of inputs (independent variable) to a set of possible outputs (dependent variable) where each input is related to exactly one output

we know that

The set of the function is { (-4, 2), (3, 6), (4, 3), (x, y) }

The ordered pair (x, y) = (4, -3)

could not be included, because for the input value of x=4, the function would have two output values (y=-3,y=3) and remember that each input is related to exactly one output

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
