In general,
Domain ==> x-values ==> {6, -2, 2, 5}
Range ==> y-values ==> {2, -4, -1, -7}
And since for every x you get one and only one y, it is a function.

{(6,2),(-2,-4),(2,-1),(5,-7)}
domain:{6,-2,2,5}
range:{2,-4,-1,-7}
It is a function because for each each value of the first component of the
ordered pairs,there is exactly one value of the second component.
