Focus and vertex of a parabola
WebThis video tutorial provides a basic introduction into parabolas and conic sections. It explains how to graph parabolas in standard form and how to graph parabolas with the focus and directrix.... WebFor any parabola, if the vertex is the point (h, k), then the focus is (h, k + (1/4a)), where a is the quadratic coefficient of y = ax 2 + bx + c. Since the vertex and focus are on the same vertical line (the axis of symmetry), it …
