Answer:
{-3, 4, 8, 10, 11}

The ordered pairs are usually defined as (input, output). That is, the input values of the relation are all of the first-numbers of the pairs:
{8, -3, 11, 10, 4}
We usually like to list members of a set in numerical order:
{-3, 4, 8, 10, 11} . . . . input values of the relation
