The axis of symmetry has the equation In this tutorial, you'll see how to find the axis of symmetry for a given quadratic equation. The vertex is on the axis of symmetry, so its x -coordinate is − b 2a − b 2 a.
Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share … The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. Here is an example of a quadratic equation #y=x^2-x+3# We can find the axis of symmetry by using #x=-b/(2a)#. The axis of symmetry in a quadratic equation would always be #x=-b/(2a)#. To find the y -coordinate of the vertex, we substitute x = − b 2a x = − b 2 a into the quadratic equation. Includes full solutions and score reporting.

When you're given the quadratic equation of the parabola, you can find it's vertex using the axis of symmetry. The equation of the axis of symmetry is x = h, where (h, k) is the vertex of the parabola.
In this tutorial, you'll see how to find the axis of symmetry for a given quadratic equation.
The axis of symmetry is the vertical line that goes through the vertex of a quadratic equation. There are two different formulas that you can use to find the axis of symmetry.
The graph of the parabola represented by the quadratic function y = a( x - p ) 2 + q has an axis of symmetry represented by the equation of the vertical line x = p.
The focus of a parabola can be found by adding to the y-coordinate if the parabola opens up or down. The axis of symmetry always passes through the vertex of the parabola . Substitute the known values of , , and into the formula and simplify. Another aid to use when graphing parabolas is the axis of symmetry; a parabola is symmetric about a vertical line that runs through the vertex.
One formula works when the parabola's equation is in vertex form and the other works when the parabola's equation is …
Free practice questions for Precalculus - Find the Vertex and the Axis of Symmetry of a Parabola. Answer: Explanation given below. The axis of symmetry is the vertical line that goes through the vertex of a quadratic equation. Find the axis of symmetry by finding the line that passes through the vertex and the focus .
Step-by-step explanation: The first step is to put the parabola in the form , which is the standard form of a parabola.
Note: a is the coefficient before x^2 term, b is the coefficient before x term, and c is the independent constant term The axis of symmetry divides the parabola symmetrically. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry of a parabola is the line x = − b 2a x = − b 2 a. Points on either side of the axis of symmetry that have the same y-value are equal distances from the axis.
The axis of symmetry of the parabola is the line passing through the midpoint of the roots. The axis of symmetry of a parabola does not always lie on the y-axis.
