He omitted the value "6" from the input value and added it to the output values. Also, he omitted the value "12" as an output value.
Step-by-step explanation:
Bobby didn't map the relation well. He omitted "6" which is supposed to be an input value and rather included it among the output values (y-values).
"12" was omitted also under output values.
All of these make the the relation not to be a function anymore.
If Bobby had mapped the relation well, the ordered pair would have obviously been a function as every x-value will have exactly one y-value assigned the it.
