Parity-check _ easier with the “Graph Math” application

Parity-check is a job that seems to be easy but sometimes quite difficult for some people. Today, I will introduce to you software that helps you to quickly and exactly draw a function graph.

### 1. Parity-check _ easier with the “Graph Math” application: The parity of function

• The even function accepts the vertical axis as the axis of symmetry.
• The odd function takes the origin of the coordinates axis as the center of symmetry.

### 2.Parity-check _ easier with the “Graph Math” application: Steps to consider function parity

Step 1: Find the domain of a function D

Step 2:

• If ∀x ∈D,∀(-x) ∈ D => step 3
• If ∀x ∈D, ∀(-x) ∉ D => the function is neither even nor odd.

Step 3:

• If f(x)= f( -x) => The function is an even function.
• If f(x)= -f(-x) => The function is an odd funtion.

This software is completely free on mobile phones.

Graph Math’s features are very convenient: Survey and graph function with extremely fast speed: 5 seconds, giving all the parameters of the function, …
