a) Ta có \(\lim\limits_{x\rightarrow-\infty}\dfrac{4x+1}{-x+1}=\lim\limits_{x\rightarrow-\infty}\left(\dfrac{-4+\dfrac{1}{x}}{1+\dfrac{1}{x}}\right)=-4\)

b) Ta có \(\lim\limits_{x\rightarrow2}f\left(x\right)=\lim\limits_{x\rightarrow2}\dfrac{x^2-x-2}{x-2}=\lim\limits_{x\rightarrow2}\left(\dfrac{\left(x+1\right)\left(x-2\right)}{x-2}\right)\)

\(=\lim\limits_{x\rightarrow2}\left(x+1\right)=2+1=3\)

 Để hàm số đã cho liên tục tại \(x=2\) thì \(\lim\limits_{x\rightarrow2}f\left(x\right)=f\left(2\right)=m\) hay \(m=3\).
