After writing the relationship, you will find that this is an even function.

Then, it needs to require the minimum value, and the variable is on the denominator, so when the denominator is the largest, it can get its minimum value.

Because X 4 ≥ 0, when X 4 = 0, that is, x=0, the denominator can get the maximum value and the minimum value of the function can be found.
