I thought every function needs a min. if x->C ? The function x^2 +1 also has a…

even two! +i and -i

because ( +i or -i)2 + 1 is really zero ( -1 + 1 )

but also with the help of all spirits you do not get this in 1/x

And you don’t have to look at such complicated functions, the main set of the algebra says that each non-constant polynomial in C has a zero. Of course there are plenty of functions without zero, f(x) = 1 is an example.

interesting is that the FS believes that every Fkt would have NSt in ‘C. And he believes that at 1/x

The function has no real zeros.

x^2+1 is a polynomial – the fundamental principle of the algebra applies only to polynomial functions; Exp(x) likewise has no zero points on C, just as the constant function f(x)=c with c equals zero…

Scream the function to f(x)=e^(x*ln(1/x)).
