Derivative Rules

Find the derivative of:

 $f\left(x\right)=x^9-7x^5+3x+13$  

•  $f'\left(x\right)=9x^8-35x^4+3$  

•  $f'\left(x\right)=x^8-7x^4+3$  

•  $f'\left(x\right)=9x^9-35x^5+3x$  

•  $f'\left(x\right)=9x^8-35x^4+3+13$  

Find the derivative of:

 $f\left(x\right)=\frac{2}{x^2}-\frac{9}{x}$  

•  $f'\left(x\right)=-\frac{4}{x^3}+\frac{9}{x^2}$  

•  $f'\left(x\right)=-\frac{4}{x}+9$  

•  $f'\left(x\right)=\frac{2}{x^3}-\frac{9}{x^2}$  

•  $f'\left(x\right)=\frac{4}{x^3}-\frac{9}{x^2}$  

The General Power Rule says that

 $\frac{d}{dx}\left[x^n\right]=$  

•  $nx^{n-1}$  

•  $x^{n-1}$  

•  $nx^n$  

•  $x^n$  

Find the derivative of:

 $f\left(x\right)=4\sqrt{x}$  

•  $f'\left(x\right)=\frac{2}{\sqrt{x}}$  

•  $f'\left(x\right)=2\sqrt{x}$  

•  $f'\left(x\right)=4x^{\frac{1}{2}}$
