Determine which of the mapping diagrams represents a relation that is not a function. (1 point) Responses Image with alt text: A mapping diagram with negative 2 pointing to negative 3 and 5

A mapping diagram that represents a relation that is not a function would be the one where there is a single input value pointing to multiple output values. Since the description provided does not indicate the existence of multiple output values for any input value, it is not possible to determine which image represents a relation that is not a function.
