Answer 1

I can't see the arrows in the diagram — could you upload or describe which element(s) in A point to which element(s) in B?

Meanwhile, here are the two possible ways to fill the blanks depending on the diagram:

If the diagram is a function:
"The mapping diagram above is a function since each element in A is paired with exactly one element in B, where a function must assign exactly one output to each input."

If the diagram is not a function (because some input has two outputs):
"The mapping diagram above is not a function since [element] in A is paired with more than one element in B (for example, [element] maps to both [value1] and [value2]), where a function must assign exactly one output to each input."

Replace [element], [value1], [value2] with the actual values from the diagram (e.g. "3 maps to both -4 and 0") and I can confirm.
