Question

1. {(0, 2), (1, 3), (2, 4), (3,5)}Domain:Range:Function?

Answer 1

We have four points.

These points represent a function because there is one and only value of y for every value of x.

Domain: all the values of x.

$x\in\lbrack0,1,2,3\rbrack$

Range: all the values of y.

$y\in\lbrack2,3,4,5\rbrack$

It is a function.
