**algebra precalculus How do I find the vertex form**

Given - Vertex #(-2,1)# Directrix #x=1# The vertex is in the 2nd quadrant. The directrix is parallel to the y-axis. So, the parabola opens to the left.... The vertex of this parabola is at (h, k). The If a parabola has a horizontal axis, the standard form of the equation of the parabola is this: (y - k) 2 = 4p(x - h), where pâ‰ 0. The vertex of this parabola is at (h, k). The focus is at (h + p, k). The directrix is the line x = h - p. The axis is the line y = k. If p > 0, the parabola opens to the right, and if p < 0, the parabola opens to

**How do you find an equation of the parabola with vertex**

Find â€˜theâ€™ parabola in standard form passing through the point $\,(1,1)\,$. This is a faulty question; it does not describe a unique parabola, as shown at right. There are two parabolas matching the given information: $\,y = x^2\,$ and $\,x = y^2\,$.... 3/08/2012Â Â· Best Answer: Vertex and focus lie on the line x = 0 The axis of symmetry is a vertical line Equation of parabola is (x-h)^2 = 4p(y-k)

**The Parabola · Precalculus**

One way to find the vertex of a parabola is to turn the standard form of the quadratic equation into vertex form by completing the square. The primary difference between solving a quadratic by completing the square and putting an equation into vertex form is â€¦... The second shortcut method for finding the coordinates of the vertex of a parabola is even quicker, but the reason it works is a little more complex. Let's compare the general vertex form of a quadratic function with the general standard or polynomial form.

**How do you find an equation of the parabola with vertex**

The vertex form of a parabola's equation is generally expressed as: y = a(x-h) 2 +k. (h,k) is the vertex as you can see in the picture below. If a is positive then the parabola opens upwards like a regular "U".... EXAMPLE 4 Finding the features of a parabola from standard form Find the vertex, focus, and directrix of the parabolay 3x 2 9x 5, and determine whether the parabola opens upward or downward.

- 3/08/2012Â Â· Best Answer: Vertex and focus lie on the line x = 0 The axis of symmetry is a vertical line Equation of parabola is (x-h)^2 = 4p(y-k)
- 17/04/2007Â Â· Best Answer: I assume that this question assumes y = f(x). That is the parabola has "standard orientation", which means that its axis of symmetry is parallel to the y-axis. If you don't assume that, then you don't have enough information to answer. The general form for a parabola in standard â€¦
