Question

Consider the following relation: (1,12) ,(3, 8) , (3, 11) , (6, 9) , (7, 11) . Whichordered pair could be removed so thatthe relation is a function?Group of answer choices(7, 11)(3, 8)

Answer 1

Step 1:

A function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Step 2:

Every input of a function must have a unique output.

Hence, input value 3 has two outputs 8 and 11, hence not unique.

Final answer

( 3 , 8 ) should be removed
