I need help with this

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.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

answer: i think you should do the math and pay attention in class : )

step-by-step explanation:

that is truly what   think but if i get the answer i will
