WebSteps to Find Vertex Focus and Directrix Of The Parabola Step 1. Determine the horizontal or vertical axis of symmetry. Step 2. Write the standard equation. Step 3. Compare the given equation with the standard equation and find the value of a. Step 4. Find the focus, vertex and directrix using the equations given in the following table. WebIf you have the parabola written out as an equation in the form y = 1/ (2 [b-k]) (x-a)^2 + .5 (b+k) then (a,b) is the focus and y = k is the directrix. This is for parabolas that open up or down, or vertical parabolas. For those that open left or right it is diffeent.
