**Convert Parabolic Equations to the Standard Form dummies**

Hi Tracy — One way is to start by finding the vertex form of the parabola, and then convert it to standard form. First, note that the directrix is y=”something”, and is a horizontal line, meaning that the parabola opens either upward or downward.... And a parabola has this amazing property: Converting y 2 = 5x to y 2 = 4ax form, we get y 2 = 4 (5/4) x, so a = 5/4, and the focus of y 2 =5x is: F = (a,0) = (5/4,0) The equations of parabolas in different orientations are as follows: y 2 = 4ax. y 2 = −4ax. x 2 = 4ay. x 2 = −4ay.

The vertex form for parabolas is convenient for graphing, but oftentimes you'll be given the equation in the usual quadratic form instead. f(x) = ax 2 + bx + c how to tell boy or girl ultrasound pictures If our parabola is opening either up or down, we use the standard form that begins with the x, and if our parabola opens sideways, we use the standard form that begins with y.

Open Microsoft Excel. In cell A1, type this text: Graph of y = 0.5(x-1)2 – 3. You may enter the general form of the equation if you wish instead of the standard form. Remember to
