Answer & Step-by-step explanation:
If your relation has some point (x1, y1), the inverse relation has the point (y1, x1). For example, one of the points of your relation is (-1, 0), so (0, -1) will be a point in the inverse relation.
A relation is a function if it does not contain two or more points with the same x-value.
(The relation shown in the graph is NOT a function, but its inverse relation IS a function.
B. (0,-1), (2,1), (-2,1), (3,3), (-3,3); inverse is a function is the answer.
