You can put this solution on YOUR website!
{(5,6),(5,7),(6,6),(6,7)}
if you need 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.
and 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.
if you ask is it function, answer is: it is not a function, because (5,6)and (5,7) both occur within its parameters
same is with (6,6),(6,7)
