We're going to explore the equation of a parabola y=a x 2 b xc for different values of a, b, and c First, let's look at the graph of a basic parabola y=x 2, where a =1, b =0, and c =0 Notice the graph opens up, the vertex is at x=0, and the yintercept is at y=0Answer and Explanation 1 We are given the parabola with equation (x1)2 = 4(y−1) ( x 1) 2 = 4 ( y − 1) and we are asked to determine the equation of the directrix of this parabola ForParabola Opens Right Standard equation of a parabola that opens right and symmetric about xaxis with vertex at origin y 2 = 4ax Standard equation of a parabola that opens up and symmetric about xaxis with at vertex (h, k) (y k) 2 = 4a(x h) Graph of y 2 = 4axThe x coordinate of the vertex is the equation of the axis of symmetry of the parabola The vertex of the parabola is ( 2, 1) So, the

Answer (1 of 7) Yes, its axis of symmetry is the xaxis If you have a quadratic equation in two unknowns, Ax^2BxyCy^2DxEyF=0 you can tell if the curve it represents is a parabola or not by its discriminant B^24AC If the discriminant is 0, it's a parabola;Consider a parabola y 2 = 4 a x, the length of focal chord is l and the length of the perpendicular from vertex to the chord is p then View solution The point on the parabola y 2 = 6 4 x which is nearest to the line 4 x 3 y 3 5 = 0 has coordinates View solution(i) Prove that the equation y 2 2ax 2by c = 0 represents a parabola whose axis is parallel to x–axis Find its vertex and the equation of the double ordinate through the focus (ii) Find the equation of the parabola whose vertex is at (2, 1) and the directrix is x = y – 1

Consider the parabola y = x 2 Since all parabolas are similar, this simple case represents all others Construction and definitions The point E is an arbitrary point on the parabola The focus is F, the vertex is A (the origin), and the line FA is the axis of symmetry In this section we will be graphing parabolas We introduce the vertex and axis of symmetry for a parabola and give a process for graphing parabolas We also illustrate how to use completing the square to put the parabola into the form f(x)=a(xh)^2kGiven a parabola whose equation is {eq}y=x^24x3 {/eq} Then we have that {eq}a=1, b=4, c=3 {/eq} To graph the parabola we first have to find its characteristic points

Assuming you don't knowThus we can consider the parabola y 2 = 4 a x y^2=4ax y 2 = 4 a x having been translated 2 units to the right and 2 units upward Since the distance between the focus and the vertex is 7, and the parabola opens rightwards, we have a = 7 a=7 a = 7 Therefore the equation of the parabola is (y − 2) 2 = 4 ⋅ 7 ⋅ (x − 2) (y − 2) 2 = 28 (xLike the ellipse and hyperbola, the parabola can also be defined by a set of points in the coordinate planeA parabola is the set of all pointslatex\,\left(x,y\right)/latex in a plane that are the same distance from a fixed line, called the directrix, and a fixed point (the focus) not on the directrix
