For what real value of  $$\textcolor{red}{N}$$  does the range of the function

$$\textcolor{red}{y = f(x) = \frac{4x^2 + Nx + N}{x + 1}}$$
where  $$\textcolor{red}{x}$$  ranges over all real numbers except  $$\textcolor{blue}{-1}$$  consist of all real numbers except for a single interval of the form $$\textcolor{green}{-L < y < L}$$?
