Given the polynomial

 $f\left(x\right)=3x^3-2x^2+x-1$  , identify the end behavior:

•  $As\ x\rightarrow-\infty,\ f\left(x\right)\rightarrow\infty$  
   $As\ x\rightarrow\infty,\ f\left(x\right)\rightarrow\infty$  
  

•  $As\ x\rightarrow-\infty,\ f\left(x\right)\rightarrow-\infty$  
   $As\ x\rightarrow\infty,\ f\left(x\right)\rightarrow-\infty$  
  

•  $As\ x\rightarrow-\infty,\ f\left(x\right)\rightarrow-\infty$  
   $As\ x\rightarrow\infty,\ \ f\left(x\right)\rightarrow\infty$  
  

•  $As\ x\rightarrow-\infty,\ f\left(x\right)\rightarrow\infty$  
   $As\ x\rightarrow\infty,\ f\left(x\right)\rightarrow-\infty$
