**Finding the Equation of a Parabola Given Focus and Directrix**

You can draw a bunch of concentric circles around the focus, with radii 1, 2, 3, and so on. Also, draw a bunch of lines parallel to the directrix, at distance 1, 2, 3, etc. from the directrix (on the same side as the focus). If circle #n intersects line #n, then those points of intersection are both n units from the focus and n units from the directrix, so they belong on the parabola. Each... Topic 3 Quadratic Functions • • The orientation of a parabola can be found from its equation. Example The parabola y x2 is concave up. To see this, imagine how the value of y will change when we substitute very large x-values into the equation, such as x = 1 000, x = 1 000 000, x = 1 000 000 000, etc. As x is given larger and larger values, the value of y becomes very large and

## How To Draw A Parabola Given An Equation

### The basic information about a parabola is its vertex and whether it opens upward or downward.

- However, as noted earlier most parabolas are not given in that form. So, we need to take a look at how to graph a parabola that is in the general form. So, we need to take a look at how to graph a parabola that is in the general form.
- Given the information from the graph, we can determine the quadratic equation using the points of the vertex, (-1,4), and the point on the parabola, (-3,12). Step …
- The key features of a parabola are its vertex, axis of symmetry, focus, directrix, and latus rectum. See . When given a standard equation for a parabola centered at the origin, we can easily identify the key features to graph the parabola.
- A variable point on the parabola is given by (2ap,ap2), for constant a and parameter p. Conversion into Cartesian equation Rearrange (1) to give: p = x 2a (3) Then substitute (3) into (2): y = a x 2a 2 = x2 4a x = 4ay which is the equation of a parabola with vertex (0,0) and focal length a. Gradient of Tangent The gradient of the tangent to x2 = 4ay at P(2ap,ap2) is p . y = x2 4a ? m = y0
