The general method of judging odd and even monotony by high school exponential function RT

Even exponents are even functions
The exponent is odd and the function is odd
There are still many situations that need to be analyzed in detail
When the index is not an integer, it is signed with a root. If it is 1.5, there will be a root 2. At this time, X can not be negative, so parity is not involved. If it is 4 / 3, with a root 3, it can be negative, like this: x3 √ X
X is an odd function, 3 √ x is also an odd function, odd or even is an even function
The simplest is to put in several generations, such as 1 and - 1, 2 and - 2
If y is the same, it is an even function and Y is an odd function
Of course, many non odd and non even functions should be careful
