Answers: 1
![\bf \textit{parabola vertex form}\\\\ \boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\ x=a(y-{{ k}})^2+{{ h}}\qquad\qquad vertex\ ({{ h}},{{ k}})\\\\ -----------------------------\\\\ y=a(x-h)^2+k\qquad \begin{cases} h=-2\\ k=-3 \end{cases}\implies y=a[x-(-2)]^2-3 \\\\\\ y=(x+2)^2-3](/tpl/images/0384/2019/5e440.png)
