If the relation is a function, list the domain and range. If the relation is not a function, choose "not a function".

C = { (9, 1) (8,-3) (7,5) (-5,3) }

Domain: 19, 8, 7,-5) Range: (1.-3, 5, 3]

Domain: [1, - 3, 5, 3) Range: 19.8.7.-5) not a function

D = {-5, 7, 8, 9}

R = {-3, 1, 3, 5}

Step-by-step explanation:

Since 'C' does not repeat any domain values, it is a function.

The x-values of a function are the domain.

{ (9, 1) (8,-3) (7,5) (-5,3) }

The domain is {-5, 7, 8, 9}.

The y-values of a function is the range.

{ (9, 1) (8,-3) (7,5) (-5,3) }

The range is {-3, 1, 3, 5}.

Domain: {9, 8, 7,-5} Range: {1,-3, 5, 3}

Step-by-step explanation:

The domain is the input values or the x values

The range is the output values

This is a functions since no inputs go to more than one output

Domain: {9, 8, 7,-5} Range: {1,-3, 5, 3}
