**22+ How To Sketch A Parabola
PNG**. In the left graph, the value of a = 1, b = 0, and c = 0. The basic parabola, y = x2, looks like this (left):

You'll identify the form of the equation as standard form or an alternative form, then find the vertex and two other points on the parabola, then sketch its graph. Nothing about directrix and focus in this video (see part 2 for that). Please tell me how to do it for this.

### The set of points in a parabola are equidistant from a fixed line.

Nothing about directrix and focus in this video (see part 2 for that). When graphing a parabola, it is not always necessary to graph them exactly. You'll identify the form of the equation as standard form or an alternative form, then find the vertex and two other points on the parabola, then sketch its graph. After determining the vertex, plot it on your graph.
