How to Find the Vertex of a Quadratic

The vertex of the quadratic is located at (h, k), where h and k are the numbers in the transformation form of the function.

To find the horizontal coordinate of the formula for h, is used.

To find the vertical coordinate the k, formula is used. To find k you need to substitute x for the horizontal coordinate h after it's found.

For this example problem 2 = a, -8 = b, and 12 = c.

Use the formula to find h.

After h is found, go back to the original problem and input the answer to h where x is.

After you find h & k write it out in interval notation and pat yourself on the back
