Question

Answer 1

4/ Ta có: \(\lim\limits_{x\rightarrow\infty}\dfrac{2x^2+3}{x^3-2x+1}=\lim\limits_{x\rightarrow\infty}\dfrac{\dfrac{2}{x}+\dfrac{3}{x^3}}{1-\dfrac{2}{x^2}+\dfrac{1}{x^3}}=\dfrac{0}{1}=0\)

Answer 2

\(\lim\limits_{x\rightarrow\infty}\dfrac{2x^2+3}{x^3-2x+1}\)

\(=\lim\limits_{x\rightarrow\infty}\dfrac{\dfrac{2}{x}+\dfrac{3}{x^3}}{1-\dfrac{2}{x^2}+\dfrac{1}{x^3}}=0\)
