Work Step by Step
Step 1. Graph the equation as shown in the figure.
Step 2. Rewrite the equation as $y^2-2y+1=2x+5+1$ or $(y-1)^2=2(x+3)$; we have $p=\frac{2}{4}=\frac{1}{2}$.
Step 3. As the vertex is at $(-3,1)$, the focus is at $(-3+\frac{1}{2}, 1)$ or $(-\frac{5}{2},1)$ and the directrix is $x=-3-\frac{1}{2}=-\frac{7}{2}$ as shown in the figure.
