.

Answer 1

I can't see the mapping diagram — could you either upload it or list the arrows (e.g. 7 → 2, 8 → −1, 3 → 6)?

Meanwhile, here are two ready-to-use completions depending on what the diagram shows:

If each element of A has exactly one arrow:
"The mapping diagram above is a function since each element in A maps to exactly one element in B where there are no elements of A with more than one image."

If some element of A has two arrows (so one input has two outputs):
"The mapping diagram above is not a function since [element] in A maps to more than one element in B where there is more than one output for that input."
(Replace [element] with the actual element, e.g. 7.)

Send the actual mappings and I will fill the blanks precisely.
