WebWhat are h and k in Vertex Form? h and k are the Vertex x- and y- coordinates of the Graph of a Quadratic Equation. They give the Location of a Minimum (when a>0) or Maximum (when a<0). You may also think of h and k as shifts/transformations: Shifting the Standard Parabola y=x² h units right yields y=(x-h)². Shifting it k units up yields y=(x ... WebIf the quadratic is written in the form y = a(x − h) 2 + k, then the vertex is the point (h, k). This makes sense, if you think about it. The squared part of y = a(x − h) 2 + k is always positive (for a right-side-up parabola), unless it's zero. So you'll always have that fixed value k, and then you'll always be adding something to it to ... phosphate oralWebStep 1: Identify {eq}h, k, {/eq} and {eq}a {/eq} for the parabola in vertex form {eq}y = a(x-h)^2 + k {/eq} through comparison of the constants.
