## What is a line of symmetry on a graph?

The axis or line of symmetry is an imaginary line that runs through the center of a line or shape creating two perfectly identical halves.

In higher level mathematics, you will be asked to find the axis of symmetry of a parabola.

This is a parabola, a u-shaped line on the graph..

## How do you know what symmetry a function has?

Test for symmetry about the x-axis: Replace y with (-y). Simplfy the equation. If the resulting equation is equivalent to the original equation then the graph is symmetrical about the x-axis.

## What does origin symmetry look like?

Mathwords: Symmetric with Respect to the Origin. Describes a graph that looks the same upside down or right side up. Formally, a graph is symmetric with respect to the origin if it is unchanged when reflected across both the x-axis and y-axis.

## How do you identify the domain and range of a function?

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

## Is function even or odd?

You may be asked to “determine algebraically” whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

## How do you determine if it is a polynomial function?

In particular, for an expression to be a polynomial term, it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions.

## How find the range of a function?

The domain of a function is the set of all acceptable input values (X-values). The range of a function is the set of all output values (Y-values).

## How do you know if something is symmetric with respect to the origin?

A graph will have symmetry about the origin if we get an equivalent equation when all the y ‘s are replaced with –y and all the x ‘s are replaced with –x .

## Is Origin symmetry odd or even?

Odd functions Another way to visualize origin symmetry is to imagine a reflection about the x-axis, followed by a reflection across the y-axis. If this leaves the graph of the function unchanged, the graph is symmetric with respect to the origin. For example, the function g graphed below is an odd function.

## How do you tell if a graph is a function?

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

## What is the symmetry of a function?

Functions can be symmetrical about the y-axis, which means that if we reflect their graph about the y-axis we will get the same graph. There are other functions that we can reflect about both the x- and y-axis and get the same graph. These are two types of symmetry we call even and odd functions. Created by Sal Khan.

## Does a circle have origin symmetry?

with respect to the origin. Solution: This circle relation has symmetry with respect to the y-axis, x-axis, and the origin. … Since f(x) = f(-x), the function is even, and its graph has symmetry with respect to the y- axis.

## How do you find the domain?

For this type of function, the domain is all real numbers. A function with a fraction with a variable in the denominator. To find the domain of this type of function, set the bottom equal to zero and exclude the x value you find when you solve the equation. A function with a variable inside a radical sign.
