f(x)=x^-4x+4
This is not a quadratic as written.
f(x)=x^{-4x}+4
It is an exponential function .

Unless the OP actually meant:f(x) = x^2 - 4x + 4
The symbol '^' means 'raised to the power of', and not 'squared' :)
Anyway, completing the square is the method you usually go by. (that is putting the quadratic in the form f(x) = a(x-b)^2 - c)
