Answer:
(−4,−27)
Explanation:
* Get the equation in the form y = ax2 + bx + c.
* Calculate -b / 2a. This is the x-coordinate of the vertex.
* To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
Rewrite in vertex form and use this form to find the vertex (h,k).
Vertex is = (−4,−27)
