Key Takeaways The graph of any quadratic equation y = a x 2 b x c, where a, b, and c are real numbers and a ≠ 0, is called a parabola;So, the equation will be x 2 = 4ay Substituting (3, 4) in the above equation, (3) 2 = 4a(4) 9 = 16a a = 9/16 Hence, the equation of the parabola is x 2 = 4(9/16)y Or 4x 2 = 9y Go through the practice questions given below to get a thorough understanding of the different cases of parabolas explained above Practice Problems 1You can put this solution on YOUR website!

Finding the focus of a parabola given its equation If you have the equation of a parabola in vertex form y = a ( x − h) 2 k, then the vertex is at ( h, k) and the focus is ( h, k 1 4 a) Notice that here we are working with a parabola with a vertical axis of symmetry, so the x coordinate of the focus is the same as the x coordinate ofAnd y = −√ x (the bottom half of the parabola) Here is the curve y 2 = x It passes through (0, 0) and also (4,2) and (4,−2) Notice that we get 2 values of y for each value of x larger than 0 This is not a function, it is called a relationThis parabola is in vertex form, so I can tell that it opens up and has a vertex of (4,2) Next, pick some points and determine the yvalue for each one It

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 symmetryIn this case, the equation of the parabola comes out to be y 2 = 4px where the directrix is the verical line x=p and the focus is at (p,0) If p > 0, the parabola "opens to the right" and if p 0 the parabola "opens to the left" The equations we have just established are known as the standard equations of a parabolaThe graph of y = x 2 is a parabola that opens upwards The vertex of this parabola is at the point where x = 0 y = x 2 If you change x to x 5 so the equation is y = (x 5) 2 then the vertex is at the point where x 5 = 0, that is at x = 5 Thus a change from x to x 5 is a translation of 5 units to the right y = (x 5)2
