Question

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

Answer 1

Answer:

a-is a function

the domain is:[-3,1]

the range is :[-4,0]

b- is not a function

Answer 2

Answer:

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.
