b)
Since f(x) is really "y", the transformation reflects each y value to it's opposite value. In other words, it takes a point like (0,1) and reflects it to (0,-1) (notice the y value is the opposite). So in general it takes (x,y) and reflects it to (x,-y)

So if P is (0,-1), then will take the opposite of the y coordinate and reflect the point to (0,1)

So the new coordinates of P is (0,1)
