what is h and k in a parabola h k is the vertex of the parabola and x h is the axis of symmetry the h represents a horizontal shift how far left or right the graph has shifted from x 0 the k represents a vertical shift how far up or down the graph has
If the parabola is vertical then the axis of symmetry passes through the vertex and is the vertical line x h If the parabola is sideways then the axis of symmetry passes through the vertex and is the horizontal line y k The general equation of a parabola is given by y a x h 2 k or x a y k 2 h Here h k denotes the vertex y a x h 2 k is the regular form x a y k 2 h is the sidewise form

You can use this vertex calculator to transform that equation into the vertex form which allows you to find the important points of the parabola its vertex and focus The parabola equation in its vertex form is y a x h k The Vertex formula of a parabola is used to find the coordinates of the point where the parabola crosses its axis of symmetry The vertex is the point h k As we know the standard equation of a parabola is y ax 2 bx c
To graph a parabola we find the vertex of the parabola and the axis of symmetry and then sketch the curve For the equation of the parabola y ax 2 bx c the x In this concept we will address parabolas where the vertex is h k learn how to find the focus directrix and graph Recall that the equation of a parabola is x 2 4 p y or y 2

The parabola is translated h units to the right if h 0 and h units to the left if h 0 The parabola is translated k units upward if k 0 and k units downward if k 0 The coordinates of the vertex are h k The axis of A parabola is defined as the locus or collection of points equidistant from a given point the focus and a given line the directrix Another important point is the vertex or turning point of the parabola If the equation of a parabola is given in
We know that the equation of a parabola in vertex form can be either of the form y a x h 2 k up down or of the form x a y k 2 h left right Let us see the steps to find the vertex of This lesson covers graphing and writing the equation of a parabola when the vertex is h k
