Given the parabola equation y-23/4=-1/3(x-1)^2, Sal finds the parabola's focus and directrix using the general formula for a parabola whose focus is (a,b) and directrix is y=k.

Finding The Focus and Directrix of a Parabola - Conic Sections

By The Organic Chemistry Tutor

This 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. The vertex of the parabola can be identified by analyzing the equation in standard form.

Deriving the Equation of a Parabola in General

By Khan Academy

Watch this video to get a better sense for how a parabola is defined geometrically, and how we can use the distance formula to help us find the equation of the parabola based on that definition. Remember, we need two distances to be the same for any point on the parabola. The distance from the point on the parabola to the focus must be the SAME as the distance from the point on the parabola to the directrix.

Parabola Equations - Graphing Parabolas - YourTeacher.com

By yourteachermathhelp

For a complete lesson on parabola equations and graphing parabolas, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to graph quadratic equations that are written in y -- k = a(x -- h)2 form by using the coordinates (h, k) to graph the vertex, and using the x and y-intercepts to graph the parabola. Students are reminded that to find the y-intercept, they must substitute a 0 in for x, and to find the x-intercept(s), they must substitute a zero in for y. Students are also asked to find the axis of symmetry using the formula x = h.
