3 choose a coordinate to substitute in and solve for a 4 write your final equation with a, h, and k this is a vertical parabola, so we are using the pattern our. A summary of graphing parabolas in 's quadratics learn exactly what happened in this chapter, scene, or section of quadratics and what it means perfect for acing. Step 1: find the vertex since the equation is in vertex form, the vertex will be at the point (h, k) step 2: find the y-intercept to find the y-intercept let x = 0. Graphing parabolas below you’ll find several common forms of the equation for a parabola click on the equation that best seems to match the parabolic equation you.
