Knowing how to find the vertex of a parabola enables us to write the equation of a parabola given only limited information about it. What is the vertex of a quadratic function? The vertex of a quadratic function is the vertex of the graph of that function. Given a quadratic function in ...
Steps to Find the Focus & Directrix of a Parabola Step 1: Identify the given equation and determine orientation of the parabola. Step 2: Find {eq}h, k {/eq}, and {eq}p {/eq} using the equation of the parabola {eq}{(x-h)}^2=4p(y-k) {/eq} or {eq}{(y-k)}^2=4p(x...
GeoGebra was not so useful for this task. GeoGebra will give us the equation of a parabola, but you need to know the focus and directrix first. This is not so straightforward from observations of a graph. Conclusion Finding the equation of a parabola given certain data points is a...

This is not a function since it is a one-to-many mapping. When will parabola open down? In classic geometry, it opens down when the directrix is above the focus.In analytical (coordinate) geometry, if the equation of the parabola isy = ax^2 + bx + c, it opens down if a <...

If the equation has a squared y term instead of a squared x term, the parabola will be oriented horizontally and open sideways, to the right or left, like a "C" or a backward "C." For example, the parabola y2 = x + 3 opens to the right, like a "C." 3 Find the axis of ...
Write an equation for a parabola with a vertex at the origin and directrix y=1 and focus at (3,0) How do you prove a quadrilateral is a parallelogram when you are given the vertices? Find the equation of the ellipse given: 1) Foci (0, \pm 5) 2) Vertices (0, \pm 8) ...
The revised integrand is {eq}-2x^3+4x^2 {/eq}, which has the same zeros as the function we solved in step {eq}1 {/eq} to find the values of {eq}x {/eq}, which are {eq}x=0 \textrm{ and } x=2 ...
