Question

Is this graph a function? Picture included below.

Answer 1

I'm asking about the second one down.

Answer 2

The V shaped one with the points and an open circle

Answer 3

There are two points with the same y-value.
To be 1 to 1 the graph must pass the vertical line test and the horizontal test.

There can be no "two timing" xs or "two timing" ys.
