Q. Look at this set of ordered pairs:(14,2)(−19,16)(5,16)(−19,10)Is this relation a function?Choices:(A) yes(B) no
Identify repeated x-value: Notice that the x-value –19 is repeated with different y-values (16 and 10).This means two different outputs for the same input, which violates the definition of a function.
Violation of function definition: Since a function must have only one output for each input, the relation is not a function.
