no, this set of ordered pairs does not represent a function. It violates the vertical line test. i.e. there exist two images for -3.

anonymous · Answer

In order for a relation to be considered a function, each element in the domain (in this case (1,-3,-2, and 6) MUST map to a UNIQUE element in the codomain.
