Question 303266: what is the domain and range for each relation? {(5,6),(5,7)(6,6),(6,7)}

You can put this solution on YOUR website!
To find the domain, make a set out of all the first coordinates:
{5,5,6,6}
Eliminate all the duplicates
{5,6}
That's the domain.
To find the range, make a set out of all the second coordinates:
{6,7,6,7}
Eliminate all the duplicates
{6,7}
That's the range.
That's all there is to it!
