Using the fixed point concept, it is found that f(x) has 3 real fixed points.
-------------------------------
The fixed points of a function f(x) are the values of x for which:
![f(x) = x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x)
In this question:
![f(x) = x^5](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E5)
Then
![x = x^5](https://tex.z-dn.net/?f=x%20%3D%20x%5E5)
![x^5 - x = 0](https://tex.z-dn.net/?f=x%5E5%20-%20x%20%3D%200)
![x(x^4 - 1) = 0](https://tex.z-dn.net/?f=x%28x%5E4%20-%201%29%20%3D%200)
Applying subtraction of perfect squares, ![x^4 - 1 = (x^2 - 1)(x^2 + 1)](https://tex.z-dn.net/?f=x%5E4%20-%201%20%3D%20%28x%5E2%20-%201%29%28x%5E2%20%2B%201%29)
Again, ![x^2 - 1 = (x - 1)(x + 1)](https://tex.z-dn.net/?f=x%5E2%20-%201%20%3D%20%28x%20-%201%29%28x%20%2B%201%29)
Then
![x(x^4 - 1) = 0](https://tex.z-dn.net/?f=x%28x%5E4%20-%201%29%20%3D%200)
![x(x - 1)(x + 1)(x^2 + 1) = 0](https://tex.z-dn.net/?f=x%28x%20-%201%29%28x%20%2B%201%29%28x%5E2%20%2B%201%29%20%3D%200)
There are 3 real fixed points,
