Find the Symmetry (x+2)/(x^2+x-20)


Step 1
Write as an equation.

Step 2
There are three types of symmetry:
1. X-Axis Symmetry
2. Y-Axis Symmetry
3. Origin Symmetry

Step 3
If exists on the graph, then the graph is symmetric about the:
1. X-Axis if exists on the graph
2. Y-Axis if exists on the graph
3. Origin if exists on the graph

Step 4
Factor using the AC method.

Consider the form . Find a pair of integers whose product is and whose sum is . In this case, whose product is and whose sum is .
Write the factored form using these integers.

Step 5
Split the fraction into two fractions.

Step 6
Check if the graph is symmetric about the -axis by plugging in for .

Step 7
Since the equation is not identical to the original equation, it is not symmetric to the x-axis.
Not symmetric to the x-axis

Step 8
Check if the graph is symmetric about the -axis by plugging in for .

Step 9
Move the negative in front of the fraction.

Step 10
Since the equation is not identical to the original equation, it is not symmetric to the y-axis.
Not symmetric to the y-axis

Step 11
Check if the graph is symmetric about the origin by plugging in for and for .

Step 12
Move the negative in front of the fraction.

Step 13
Since the equation is not identical to the original equation, it is not symmetric to the origin.
Not symmetric to the origin

Step 14
Determine the symmetry.
Not symmetric to the x-axis
Not symmetric to the y-axis
Not symmetric to the origin

Step 15
