Just do a regression; https://www.desmos.com/calculator/zh5jbhwmfz, Uh that doesn't form a parabula. Here's a a quick video tutorial on graphing movable points in the Desmos Graphing Calculator (https://www.desmos.com/calculator).You can find more how-to vid. Add Question Title Enter a title for the question. What is the equation of the parabola? You can change a static point to a movable point by clicking and long-holding the icon next to the expression list. To view the correct answer in the Preview pane, click the Show Answers checkbox [3]. To move a parabola V units up, you would substitute y H for Y in the corresponding quadratic equation. In real-world terms, a parabola is the arc a ball makes when you throw it, or the distinctive shape of a satellite dish. Changing the shape of a parabola involves adding and multiplying by certain numbers but the trick is to know which numbers to use and when to use them. % of people told us that this article helped them. Lets say you have the following equation: 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 y. A little simplification gets you the following: 5 = a(2)2 + 2, which can be further simplified to: Now that you've found the value of a, substitute it into your equation to finish the example: y = (3/4)(x - 1)2 + 2 is the equation for a parabola with vertex (1,2) and containing the point (3,5). Select the remaining details for your question using the drop-down menus [1]. These variables are usually written as x and y, especially when you're dealing with "standardized" shapes such as a parabola. Parabola defined by 3 points. Once the question is published to an item bank, you can add the question to an assessment. Post your question to get help from fellow Community members. Lisa studied mathematics at the University of Alaska, Anchorage, and spent several years tutoring high school and university students through scary -- but fun! Reddit's automated bots frequently filter posts it thinks might be spam. Hence, the direction of parabola is determined by sign of . "I was attempting to find a site that helped me graph a parabola. Expert Source (3 Key Ideas To Know). To test the auto-grading tool, click and drag the points [1]. References. To make a parabola wider, make the value of a (or |a|) larger. You can change the concavity by multiplying the quadratic equation by a negative number (or make a < 0). This is called a width change (it may also change the location of the parabolas vertex). For example, if we have the quadratic f(x) = x2, then we would plug in Wx for x to get f(Wx) = W2x2. For example, if we have the quadratic f(x) = x2, then we would multiply by -1 on the right side to get g(x) = -x2. Uh that doesn't form a parabula. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/7e\/Graph-a-Parabola-Step-1-Version-2.jpg\/v4-460px-Graph-a-Parabola-Step-1-Version-2.jpg","bigUrl":"\/images\/thumb\/7\/7e\/Graph-a-Parabola-Step-1-Version-2.jpg\/aid4162801-v4-728px-Graph-a-Parabola-Step-1-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
