Let \( f: D \rightarrow R \) be defined as \( : f(x)=\frac{x^{2}+2 x+a}{x^{2}+4 x+3 a} \) where \( D \) and \( R \) denote the domain of \( f \) and the set of all real numbers respectively. If \( f \) is surjective mapping, then the complete range of \( a \) is :https://bit.ly/YTAI_PWAP https://www.pw.live
