## How to test for symmetry for the origin

### To test for symmetry around the origin, we need to determine if a function remains unchanged when we replace each coordinate (x, y) with its opposite (-x, -y)

To test for symmetry around the origin, we need to determine if a function remains unchanged when we replace each coordinate (x, y) with its opposite (-x, -y).

To check for symmetry around the origin, follow these steps:

1. Replace x with -x and y with -y in the given function.

– For example, if the function is f(x, y) = x^2 + y^2, replace x with -x and y with -y to get f(-x, -y) = (-x)^2 + (-y)^2.

2. Simplify the function obtained in step 1.

– Using the example, f(-x, -y) simplifies to f(x, y) = x^2 + y^2.

3. Compare the original function to the simplified function.

– If the original function is equal to the simplified function after replacing x with -x and y with -y, then the function is symmetric around the origin.

For example, let’s test symmetry for the origin in the function f(x, y) = 2x – 3y.

1. Replace x with -x and y with -y:

f(-x, -y) = 2(-x) – 3(-y) = -2x + 3y.

2. Simplify the function:

f(-x, -y) simplifies to f(x, y) = -2x + 3y.

3. Compare the original function to the simplified function:

The original function f(x, y) = 2x – 3y is not equal to the simplified function f(x, y) = -2x + 3y. Therefore, the function is not symmetric around the origin.

In conclusion, to test for symmetry around the origin, we need to replace x with -x and y with -y and check if the original function is equal to the simplified function.
