How to Find the Vertex of a Quadratic Function – A Step-by-Step GuideThe calculated y-value upon substitution into the equation y = a x 2 + b x + c gives the y-coordinate of the vertex. Combine the x and y values to get the vertex’s coordinates. The vertex will be a point (h, k), where h is the x-value and k is the y-value obtained from the previous steps.

How to Find the Vertex of a Quadratic Equation: 10 Steps - wikiHowTo find the vertex, set x = -h so that the squared term is equal to 0, and set y = k. In this particular case, you would write 3(x + 1)^2 + (-5) = y. To make x = -h, input -1 as the x value. Then you’ll get 3(-1 + 1)^2 – 5 = y, which simplifies to 3(0) – 5 = y, or -5=y. Write the vertex as (-1, -5).

5 Ways to Find the Vertex - wikiHowFigure out what the coordinates are based on the vertex equation. Recall that the vertex form of an equation is y = a(x - h)^2 + k , with (h, k) representing the coordinates of the vertex. You now have enough information to plug values into the h and k slots and complete the problem.
