Final answer:
To find the inverse of a relation, swap the positions of the elements in each pair.
Step-by-step explanation:
To find the inverse of the given relation as a set of ordered pairs, you need to swap the positions of the elements in each pair.
Original Relation: {(-2, -0.25), (-1, -0.5), (0, -1), (1, -2), (2, -4)} Inverse Relation: {(-0.25, -2), (-0.5, -1), (-1, 0), (-2, 1), (-4, 2)}
