Question

Which ordered pair can be removed so that the resulting graph represents a function?

Answer 1

Answer:

(1, 3) can be removed so that the resulting graph represents a function. A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y.

Answer 2

Step-by-step explanation:

(1, 3) can be removed so that the resulting graph represents a function.

Solution-

A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y.

Here,

X = {-5, -4, -2, 1, 2, 5}

Y = {-4, -3, -2, 1, 2, 3}

Relation from X to Y : {(-5, -3), (-4, -4), (-2, 2), (1, -2), (1, 3), (2, 1), (5, -4)}

This relation is not a function from X to Y because the element 1 in X is related to two different elements, -2 and 3

So, we have to remove either (1, -2) or (1, 3) in order to make this a function.
