Answer:

a) {(3,3),(3,4),(4,5),(4,6)}

Step-by-step explanation:

Given

(a) to (d)

Required

Which is not a function

A relation is represented as:

[tex]\{(x_1,y_1),(x_1,y_1),(x_2,y_2),...............(x_0,y_0)\}[/tex]

For the relation t be a relation, then:

[tex]x_i \ne x_j[/tex]where [tex]i \ne j[/tex]

This means that none of the x values must be related.

The first relation has 3 repeated as its value of . Hence, (a) is a relation
