SOLUTION
In the first image
Looking at the first graph, the curve at the center below agrees with
Because if you move from left to right down the curve, you will still arrive at the point where x = 1 and y = 4.5
For the second graph, if you move from the left to the point where x = 1, you get y = 1, but coming from the right, you get to a point where x = 1 and y = -2.
Hence the second graph does not agree.
For the image below
Looking at this graph, moving from the left, x = 1 at y = -3 and coming from the right, x = 1 at y = 4,
Hence this graph does not agree too.
