It is the ratio of the distance of a point from the focus, to the distance of the point from the directrix. The eccentricity of a parabola is equal to 1.Here are the formulas to find the equation of the axis, directrix, vertex, focus, and length of the latus rectum of different ...
Point (4,2)(4,2) is on the graph of a parabola with vertex at the origin (0,0)(0,0) and vertical axis. Find the focus of the parabola, graph it and label the focus and graph the directrix. Solution to Example 1 The equation of a parabola with vertical axis at whose vertex ...
and they know that students often have the idea that all answers are always either whole numbers or "neat" fractions like one-half. For instance, if the calculator screen estimates a vertex as being at(0.48, 0.98), many students will assume that the answer must "really" be(0.5, 1), in...

You can plug x-values in to find corresponding y-values, but it's trickier to graph because the parabola will curve around a vertex (the point where the parabola turns around). To find the vertex (h,k) divide the opposite of "b" by 2a. In the equation y = 3x^2 - 4x + 5, th...
A parabola is a conic section, or a graph in the shape of a U that opens either upward or downward. A parabola opens from the vertex, which is the lowest point on a parabola that opens up, or the lowest point on one that opens down -- and is symmetrical. The graph corresponds to...
Students learn how to apply the endpoint math formula -- a derivation of the midpoint formula -- during a unit on graphing in the coordinate plane, which is typically taught in an algebra course but sometimes covered in a geometry course. To use the endp
