If a diagram has p→1, p→2, and q→3, what is the correct conclusion?

Answer and explanation

Correct answer: It is not a function

A mapping diagram represents a function only when every input has exactly one arrow leading to one output. In the given diagram, the input p points to both 1 and 2. Thus p has two different images, which violates the defining condition of a function. The input q has one image, 3, but that does not repair the failure caused by p. Therefore option A is correct. It is not a constant function because the outputs are not all the same, and it is not an identity function because the displayed input and output labels do not show p mapping to itself or q mapping to itself. Option D is false because a mapping is not automatically a function; the one-output-per-input rule must be checked.
