If a diagram has a→3, b→3, and c→4, is it a function or not?

Answer and explanation

Correct answer: Yes, it is a function

The governing definition says that a mapping is a function when every input in its domain is associated with exactly one output. Here a is associated with 3, b is associated with 3, and c is associated with 4. Each input has one and only one image, so the mapping is a function. It is specifically a many-one function because the distinct inputs a and b have the same output 3. Repeated outputs are allowed; the restriction concerns repeated inputs with different outputs. Therefore option A is correct. Options B and C confuse the prohibition on multiple outputs for one input with the allowed sharing of an output. Option D is also invalid because an output need not have several preimages.
