It can be tricky to figure out if a function is odd or even just by looking at its graph. Here are some common problems people face:
Finding Symmetry: Not every function has clear symmetry. For even functions, the graph should look the same on both sides of the y-axis. For odd functions, it should look the same if you turn it around the origin (the point where the x-axis and y-axis meet).
Complicated Shapes: Some functions have shapes that are very detailed and can make it hard to tell if they are symmetrical or not.
To make this easier, you can use some simple steps:
For even functions, check if . This means that if you flip the x-value, the y-value stays the same.
For odd functions, see if . This means that if you flip the x-value, the y-value also flips to the opposite sign.
By following these steps, you can better identify if a function is odd or even.
