Is it a function and what is the Domain and the Range

3.A.) It is a function

Domain = {-3,-2,0,1}

Range = {0,-4,0,-4}

3.B.) It is not a function

Domain = {0,1,1,4,4}

Range = {0,1,-1,2,-2}

Step-by-step explanation:

Coordinates to 3.A. are (-3,0), (-2,-4), (0,0), (1,-4)

The Domain is the set of input values which are the x values.

The Range is the set of output values which are the y values.

Coordinates to 3.B. are (0,0), ( 1,1), (1,-1), (4,2), (4,-2)

3.B. Is not a function because it has more than one of the same inputs (x values).

A Function cannot have more than one of the same input (x values).

Hope this helps.

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
