Finding a Formula for a Parabola's Vertex
Purplemath
Since you always do exactly the same procedure each time you find the vertex form, the procedure can be done symbolically (using the algebraic quadratic y = ax2 + bx + c explicitly, instead of putting in numbers), so you end up with a formula that you can use instead of doing the completing-the-square process each time.
It's up to you, whether you want to memorize the formula for the coordinates of the parabola's vertex.
You'll probably be required to "show your work" in finding the vertex.
Ask now if applying a memorized formula is acceptable. Either way, and particularly if you're expected to derive the formula yourself, here's how the formula deriviation goes:
- Derive the formula for the x-coordinate "h" of the vertex of any quadratic.
This is my generic quadratic equation.
My first step is to move the loose number (indicated by the contant c) over to the other side.
I factor out (that is, I pull out to the front) whatever is multiplied on the squared term.
Then I ma
