La parabola ha quindi equazione y −1 = 3(x −2)2, ovvero yIf the parabola is rotatedso that its vertex is (h,k) and its axis of symmetry is parallel to thexaxis, it has an equation of (y k)2= 4p (x h), where thefocus is (h p, k) and the directrix is x = h p It would also be in our best interest to cover another form that theequation of aIt has both Q Given y = 2 (x 5) 6, the vertex is Q Given 1/2 (x 4) 5, the equation of the axis of symmetry is Q A parabola has a vertex at (3,2)
Example Draw the tangent line for the equation, y = x 2 3x 1 at x=2 Given Equation = x 2 3x 1 x = 2 Solution Step 1 To find the y value, substitute the x value in given equationY = (x − 1)2 y = ( x 1) 2 Find the properties of the given parabola Tap for more steps Use the vertex form, y = a ( x − h) 2 k y = a ( x h) 2 k, to determine the values of a a, h h, and k k a = 1 a = 1 h = 1 h = 1 k = 0 k = 0 Since the value of a a is positive, the parabola opens up Opens UpIgualar y y al nuevo lado derecho Use la forma de vértice, y = a ( x − h) 2 k y = a ( x h) 2 k para determinar los valores de a a, h h, y k k Dado que el valor de a a es positivo, la parábola se abre hacia arriba Encuentra el vértice ( h, k) ( h, k) Hallar p p, la distancia desde el vértice al foco
The distance PF is equal to the distance PQ Rather than use the distance formula (which involves square roots) we use the square of the distance formula since it is also true that PF 2 = PQ 2 We get (x0) 2 (yp) 2 = (yp) 2 (xx) 2 x 2 (yp) 2 = (yp) 2 If we expand all the terms and simplify, we obtain x 2 = 4py We actually have 2 functions, y = √ x (the top half of the parabola);Free Parabola calculator Calculate parabola foci, vertices, axis and directrix stepbystep This website uses cookies to ensure you get the best experience
