Determine whether the relation represents a function. If it is a function, state the domain and range.

{(negative 3 comma 7 )comma (1 comma 3 )comma (3 comma 1 )comma (7 comma negative 1 )}

Yes, the relation is a function

Domain = {-3,1,3,7}

Range = {7,3,1-1}

Explanation:

Given

{(-3,7),(1,3),(3,1),(7,-1)}

To determine if the relation is a function or not, we check if every output has only one corresponding input.

The output are (7,3,1-1) while the input are (-3,1,3,7)

-3 ;> 7

1 > 3

3 > 1

7 > -1

It is a function since every output only has one corresponding input

To find the domain, we look at the set of input values

Domain = {-3,1,3,7}

To find the range, we look at the set of output values

Range = {7,3,1-1}

what is your question exactly? when you let me know i will gladly you. : )
