Answer:
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}
