Question

Which graph does NOT represent a function?

Answer 1

Answer:  The correct graph is (B).

Step-by-step explanation: We are given to select the graph that does NOT represent a function.

We know that

a graph will represent a function if one value of x will not correspond to more than one value of y.

From the given four graphs, we notice that

only graph B contains points with same x-values and different y-values. That is, one value of x corresponds to more than one value of y.

Some of those points are (x, y) = (3, 1), (3, 2), (3, 3), (3, 4),  .  .  .etc.

Therefore, the graph B does NOT represent a function.

Thus, option (B) is CORRECT.

Answer 2

I believe [B] is correct. Im not totally sure, but I am leaning to that
