a) {(3,3),(3,4),(4,5),(4,6)}
b) {(0,8),(8,4),(2,7),(-2,6)}
c) { (-1,3), (1,7), (7,4),(-3,8) }
d) {(-6,5),(5,1), (7,4),(-3,8) }

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:

For the relation t be a relation, then:

where

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

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

351°f
