Functions Mappings Tables and Coordinate Pairs

Given this set of ordered pairs, state the range.

• (1, 2, 3, 4, 5)

• ( 1 )

• (1, 4, 9, 16, 25)

• The range does not exist

Which of these is NOT a function?

• the mapping on the left

• the mapping on the right

• neither of these are functions

• both of these are functions

Is this a function?

• Yes because each domain value has only one range value

• Yes, because each range value has only one domain value

• No because the elements of the domain are paired with more than one element of the range

Does this mapping diagram represent a function?

• No, because an input value goes to multiple output values

• Yes, because each input goes to one and only one output
