Question 1043849
.
Please help 

Let  p(x)=x^4+3x^3-3x^2-11x-6

1. How many zeroes are there?
2. How many positive zeroes are possible?  How many negative zeroes?
3. What are the possible rational zeroes?
4. Find the zeroes.
5. Sketch a graph of p(x)
~~~~~~~~~~~~~~~~~~~~~~~~~~


<TABLE> 
  <TR>
  <TD> 

{{{graph( 330, 330, -5.5, 5.5, -5.5, 5.5,
          x^4+3x^3-3x^2-11x-6
)}}}


Plot f(x) = {{{x^4+3x^3-3x^2-11x-6}}}

  </TD>
  </TR>
</TABLE>

Can you do the rest having this plot?
