WebAnd Sal told that to obtain the vertex form the Part A ( x + B )^2 should be equal to zero in both the cases. And for that (x+ (b/2a)) should be equal to zero. And now we can derive that as follows: x + (b/2a) = 0 => x = -b/2a. And here your formula is whose deriving seems pretty daunting but is based on just simple logical reasoning.

WebWhich is the equation of a parabola with vertex (0, 0) and focus (0, 2)? Solution: Given, vertex = (0, 0) Focus = (0, 2) We have to find the equation of the parabola. The equation is of the form y = -ax 2. Directrix y = -2. As every point on parabola is equidistant from focus and directrix, the equation will be. x 2 + (y - 2) 2 = (y + 2) 2
WebFinding Vertex from Standard Form. The x-coordinate of the vertex can be found by the formula − b 2 a, and to get the y value of the vertex, just substitute − b 2 a, into the the … WebThe equation of a parabola whose vertex is given by its coordinates ( h, k) is written as follows. y = a ( x − h) 2 + k. For the point with coordinates A = ( x 0, y 0) to be on the parabola, the equation y 0 = a ( x 0 − h) 2 + k must be satified. Solve the above equation to find coefficient a. a = y 0 − k ( x 0 − h) 2.
