Step 1. Rewrite the equation as $y=(x^2+4x+4)-9=(x+2)^2-9$ Step 2. We can identify the vertex as $(-2,-9)$ and axis of symmetry as $x=-2$ Step 3. We can find x-intercepts as $x=-2\pm3$ or $x=-5, 1$ Step 4. We can find the y-intercept as $y=-5$ Step 5. We can graph the equation as shown in the figure.
