Question

Find the domain and range of this relation. is it a function?(0,0),(1,1),(2,4),(3,9),(4,-6)

Answer 1

Data: (x,y)

(0,0),(1,1),(2,4),(3,9),(4,-6)

Domain: All the x-values in the relation

Range: All the y-values in the relation

A function is a relation where each input (x-value) has only one output (y-value)

For the given relation:

Domain:

$\lbrace0,1,2,3,4\rbrace$

Range:

$\lbrace0,1,4,9,-6\rbrace$As each values of x has one corresponding value of y, it is a function
