We’re already seeing how students are using it and how faculty are using it for research. Now, let’s dive deeper into how […]

Xét  \(y=f\left( x \right)=a{{x}^{4}}+b{{x}^{3}}+c{{x}^{2}}+dx+e\Rightarrow f’\left( x \right)=4a{{x}^{3}}+3b{{x}^{2}}+2cx+d\). Từ đồ thị \(y={f}’\left( x \right)\) ta có \({f}'(x)=4ax\left( {{x}^{2}}-1 \right)=4a{{x}^{3}}-4ax.\) Vậy ta có hệ phương trình \(\begin{array}{l}\left\{ \begin{array}{l}b = 0\\2c = – 4\\d = 0\end{array} \right.a\\\Leftrightarrow \left\{ \begin{array}{l}b = 0\\c = – 2a\\d = 0\end{array} \right.\end{array}\)  \(\Rightarrow f\left( x \right)=a{{x}^{4}}-2a{{x}^{2}}+e\). Ta lại có \(f\left( 0 \right)=3f\left( 2 […]
