Answer

(G)

Work Step by Step

1. The parabola in this graph opens to the left, thus it has a general equation $4p(x-h)=-(y-k)^2$ 2. Use the vertex $(1,1)$ on the curve, we have $4p(x-1)=-(y-1)^2$ 3. Use the point $(0,3)$ on the curve, we have $4p(0-1)=-(3-1)^2$, thus $p=1$ 4. 3. Thus the answer is (G)
