Web2 Answers Sorted by: 2 From the diagram it looks as if you may be looking for a parabola with a horizontal line of symmetry and vertical directrix. This would have equation ( y − b) 2 = 4 a ( x − c). If you know three points, this gives you three equations in three unknowns ( a, b and c being required - or a, b and d if you put a c = d ).

How to Find Equation of a Parabola Sciencing
WebFinding Parabolas through Two Points Find all quadratic functions described by the equation $y = ax^2 + bx + c$ whose graph contains the two points $(1,0)$ and $(3,0)$. How are the graphs of these … WebMar 26, 2016 · Because the equation of the parabola is you can take a general point on the parabola, ( x, y) and substitute for y. Take the derivative of the parabola. Using the slope formula, set the slope of each tangent line from (1, –1) to equal to the derivative at which is 2 x, and solve for x. guymon to dodge city

WebMar 27, 2024 · So the equation of the parabola is the set of points where these two distances equal. \(\ y+b=\sqrt{(x-0)^{2}+(y-b)^{2}}\) Since distances are always positive, we can square both sides without losing any information, obtaining the following. \(\ \begin{aligned} y^{2}+2 b y+b^{2} &=x^{2}+y^{2}-2 b y+b^{2} \\ 2 b y &=x^{2}-2 b y \\ 4 b y … WebThere are 3 steps to find the Equation of the Straight Line : 1. Find the slope of the line 2. Put the slope and one point into the "Point-Slope Formula" 3. Simplify Step 1: Find the Slope (or Gradient) from 2 Points … WebThe same process would be true for a quadratic funtion (which creates a parabola). Easiest is to find the vertex, find two or more additional points around the vertex which is the same as graphing a quadratic equality. Then, determine if the parabola is solid or dashed just like a linear, and if you should shade above or below the parabola ... guymon to woodward
