Critical point of x − 5 x 1 5

If your function is x − 5 x 1 / 5 then it's not defined at 0. So 0 is not a critical point. But if it is x − 5 x 5 then yes, the critical points are 0 and 1, but also − 1.

If your function is

x - 5 x^{1 / 5}

then it's not defined at

0

. So

0

is not a critical point. But if it is

x - 5 \sqrt[5]{x}

then yes, the critical points are

0

and

1

, but also

- 1
