Which ordered pair can be removed so that the resulting graph represents a function?
a. (–2, 2)
b. (1, 3)
c. (5, –4)
d. (–4, –4)

Answer-

(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.

The correct option is b.

Step-by-step explanation:

Graph represents a relation and the coordinates of each points are,

A relation is called function if there exist a unique value of y for each value of x.

It the above relation for each value of a x there exist a unique y except (1,-2) and (1,3). If one of these point is removed, then the resulting graph represents a function.

Therefore correct option is b.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
