Even Functions : These are in *Reflectional symmetry* That is :

The Left one , here

f(-x) = f(x)

Odd functions : These are *symmetrical within the origin* That is:

The Right one , here

f(-x) = -f(x)

Thanks and have a nice day ahead

*The derivative of an even function is odd, and the derivative of an odd function is even*. The next of an even number is odd and the next of an odd number is even.

it is just named as 2 different branches of function . the result could be anything but more important is that LHS = RHS
