I don't remember learning about stating the inverse of a relation.

So, I need help stating the inverse of this relation:

(-2, -1) (0, 1) (1, 3) (1, -2) (2, 0).

(-1, -2) (1, 0) (3, 1) (-2, 1) (0, 2)

In words: Some relation acting on -2 gives -1. The inverse relation on -1 gives -2.
In symbols: If R(-2) = -1, then R{inv}(-1) = -2
