How to determine if an ordered pair is a function or not

What is the primary purpose of using ordered pairs in functional relationships?

• To calculate the sum of elements in set A

• To determine the size of set A

• To establish a connection between inputs and outputs

• To identify the elements in set B

Which condition must be met for a relationship to be considered a function?

• Each element in set B must map to a unique element in set A

• Each element in set A must map to the same element in set B

• Each element in set A must map to a unique element in set B

• Each element in set B must map to multiple elements in set A

In the example given, why is the relationship where C maps to both 2 and 3 not considered a function?

• Because 2 and 3 are not elements of set B

• Because C should map to the same element as A

• Because C maps to more than one element in set B

• Because C is not an element of set A

What happens to the function status when the input and output variables are switched?

• The relationship becomes undefined

• The relationship is no longer a function

• The relationship becomes a function

• The relationship remains a function

What is a key takeaway about input values in a functional relationship?

• Input values can map to multiple output values

• Input values must map to unique output values

• Input values should be greater than output values

• Input values are irrelevant in determining a function
