Question

The graph of a relation is given. The graph has points of (0, 6), (6, 0), (0, -6). Apply the vertical line test to determine if this relation is a function.
(1 point)
• Yes, the given relation is a function.
There is not enough information to determine whether this relation is a function.
• No, the given relation is not a function.
• The relation is a half-circle.

Answer 1

No — it is not a function. A vertical line at x = 0 hits the graph at (0,6) and (0,−6), so a vertical line intersects the relation more than once, failing the vertical line test.
