Write the equation of the parabola in the standard form and identify the vertex. Show your complete solution. x^2 - 4x = 4y + 16 by Live Like We're Dying on Apr 29, 2012 x^2 - 4x = 4y + 16 4y = x^2 - 4x - 16. Standard Form: y = (x^2)/4- x - 4. The vertex of a parabola is given by (-b/2a, f(x)). Thus x = -b/2a or -(-1)/(2*1/4) = 2. f(2) = (2^2)/4 - 2 -4 = -5. Vertex (2, -5).
Curve Art in GeoGebra by Mathematics for Teaching on Feb 2, 2012Mathematics for Teaching - This site is NOT about making mathematics easy because it isn't. It is about making it make sense because it does.GeoGebra is a great tool for learning and teaching mathematics. It also caters to frustrated artists lik...
Deriving the Equation of the Parabola by GeoGebra Applet Central on Jan 25, 2012Instructions: Move point A to adjust the position of the vertical line and move F along the x-axis as desired. Move C along the line and observe what happens.
The Parabola in Vertex Form by GeoGebra Applet Central on Dec 5, 2011Move sliders a, h, and k. What do you observe? How are a, h, and k relates to the graph's movement? Make a generalization about the relationship between the parameters a, h, and k and the movement of the appearance of the graph.
Multiplication in Parabola by GeoGebra Applet Central on Jul 10, 2011Move the points of on the parabola and observe the coordinates of the points on the axes. What conjecture can you make from your observation? This is a Java Applet created using GeoGebra from www.geogebra.org - it looks like you don't have Java i...

It’s for this reason that parabolic dishes are used to both send and receive signals over large distances. [code] [more] Orgasmic.
