Assume there exists a such that

Then either:

(i)

(ii)

(ii)

Consider (i), i.e.

Then since y is positive, y+1 is certainly positive Contradiction. Hence y<0

Consider (ii), i.e.

Then

But since y > -1, we certainly have that y+1 is positive and Contradiction. Hence y must be less than or equal to 1.

Consider (iii), i.e.

Then . Contradiction.

Hence, there exists no such .

EDIT: I don't know why I used y instead of x. Sorry.
