Does this mapping represent a function?

• No, because two inputs map to 0

• No, because two inputs map to 1

• Yes, because 0 maps to 0 and 1 maps to 1

• No, because the inputs can result in more than one output

Tell me about this table (choose 2):

• It represents a function

• It does NOT represent a function

• Because the x-values repeat

• Because the x-values do NOT repeat

Tell me about this mapping (select 2):
