**How do you find the vertex of a parabola y=x^2 Socratic.org**

19/08/2008 · Best Answer: rewrite the equation in standard form for a parabola. ( y - k ) ? = 4p ( x - h ) where the vertex is at ( h,k ) so to do that we add 2x to both sides and also subtract 5 from both sides... From here, we identify the vertex of our parabola at (-3/4, -41/8) and the +2 indicates our parabola opens upward. To shift the graph to the right by 4, we can replace x with (x-4) everywhere in our original equation (or equivalently in the standard form of our equation).

**Finding the Directrix of a Parabola Given its Vertex and**

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 of the vertex. Example 1: Find the focus of the parabola …... The vertex is the midpoint between the focus and the directrix. The eccentricity of a parabola is the distance from the focus to any point on the graph divided by the distance from that same point on the graph to the directrix.

**Parabola â€“ vertex focus directrix latus rectum**

## How To Find Vertex Of A Sideways Parabola

A vertical parabola results from a quadratic equation in which the x part of the equation is squared. To sketch the graph of a parabola, we first identify the vertex, the focus and the directrix. To do this, we first write the equation in the form (x – h)^2 = 4p(y – k), where (h, k) is the vertex and p is the distance between the vertex and the focus.

- 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 of the vertex. Example 1: Find the focus of the parabola …
- Because this is a sideways parabola, the x and y variables must be reversed. y = (-b/2a) ± [v(b? - 4ac)/2a] the x coordinate of the vertex of the parabola is:
