**Find the axis of symmetry of the function f(x)=-3x^2-6x-1**

the axis of symmetry (goes through the focus, at right angles to the directrix) The simplest equation for a parabola is y = x 2 . Turned on its side it becomes y 2 = x (or y = âˆšx for just the top half) A little more generally: y 2 = 4ax. where a is the distance from the origin to the focus (and also from the origin to directrix) Example: Find the focus for the equation y 2 =5x... 14/08/2008Â Â· Best Answer: If a graph has symmetry about the y-axis, then for each point (x, y) there is another point (-x, y) on the graph. Because of this, equations with graphs that are symmetric about the y-axis are precisely those equations where, when you plug in -x for x, you get the same equation back.

**Molecular symmetry Wikipedia**

Graph of x 2 Symmetry about y-axis. Graph of 1/x Diagonal symmetry. In other words, there is a mirror-image. Benefits. The benefits of finding symmetry in an equation are: we understand the equation better; it is easier to plot; it can be easier to solve. When we find a solution on one side, we can then say "also, by symmetry, the (mirrored value)" How to Check For Symmetry. We can often see... Symmetry The graph of an equation may be symmetrical over the x-axis, the y-axis and/or the origin. Knowing if a graph is symmetrical helps make it easier to sketch the graph of an equation.

**For a Quadratic Function find Vertex Axis of Symmetry**

The line (or "axis") of symmetry is the y-axis, also known as the line x = 0. This line is marked green in the picture. The graph is said to be "symmetric about the This line is marked green in the picture.... Given the function f(x) = -2x^2 + 8x -11 Determine the vertex; List the axis of symmetry; Calculate the y-intercept; Use the axis of symmetry and the y-intercept to find an additional point on the gra â€¦

**How Do You Find the Axis of Symmetry for a Virtual Nerd**

15/02/2011Â Â· The axis of symmetry is the vertical line in the process the vertex so x=a million The area is the set of numbers you ought to use for x - all actual numbers and the variety are the ensuing y values. because of the fact the vertex is (a million,-sixteen) and the parabola opens upward so the variety is all numbers >=-sixteen (the parabola opens up on the grounds that a is valuable)... In some cases, you will be asked to perform horizontal reflections across an axis of symmetry that isn't the x-axis. But before we go into how to solve this, it's important to know what we mean by "axis of symmetry". The axis of symmetry is simply the horizontal line that we are performing the reflection across. It can be the x-axis, or any horizontal line with the equation y y y = constant

## How To Find X Axis Symmetry

### 14/08/2008Â Â· Best Answer: If a graph has symmetry about the y-axis, then for each point (x, y) there is another point (-x, y) on the graph. Because of this, equations with graphs that are symmetric about the y-axis are precisely those equations where, when you plug in -x for x, you get the same equation back.

- 30/11/2018Â Â· It is important to find out the parabolaâ€™s vertex or starting point, as itâ€™s x-coordinate is equal to the axis of symmetry. It makes graphing the rest of the parabola much easier. It makes graphing the rest of the parabola much easier.
- So, the equation of the axis of symmetry of the given parabola is x = âˆ’ ( 5 ) 2 ( âˆ’ 2 ) or x = 5 4 . Substitute x = 5 4 in the equation to find the y -coordinate of the vertex.
- The dashed line with each of these parabolas is called the axis of symmetry. Every parabola has an axis of symmetry and, as the graph shows, the graph to either side of the axis of symmetry is a mirror image of the other side. This means that if we know a point on one side of the parabola we will also know a point on the other side based on the axis of symmetry. We will see how to find this
