How do you find the vertex of a parabola in Y?Finding Vertex of a Parabola From Standard Form. Step - 1: Compare the equation of the parabola with the standard form y = ax2 + bx + c. ... . Step - 2: Find the x-coordinate of the vertex using the formula, h = -b/2a. ... . Step - 3: To find the y-coordinate (k) of the vertex, substitute x = h in the expression ax2+ bx + c.. What is the vertex formula?The vertex form of a parabola is y = a(x-h)2 + k.
