How To Find Vertex Of A Parabola?

How do you find the vertex of a quadratic equation?

We find the vertex of a quadratic equation with the following steps:

  • 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.

What is the vertex formula?

y = a(x – h)2 + k, where (h, k) is the vertex. in y = ax2 + bx + c (that is, both a’s have exactly the same value).

How do we find vertex?

Steps to Solve

  1. Get the equation in the form y = ax2 + bx + c.
  2. Calculate -b / 2a. This is the x-coordinate of the vertex.
  3. To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
