Answer
See graph
Work Step by Step
$$x=-(y-1)^2$$
The vertex is (0,1); we know this because the equation is in vertex form. The parabola opens to the left.
Substitute values for x to find their corresponding y-values.
$$1=-(y-1)^2$$
$$1=-(y-1)$$
$$-1=y-1$$
$$y=0$$
$$-1=-(y-1)$$
$$1=y-1$$
$$y=2$$
$$(-1,0)$$
$$(-1,2)$$
