> I need to know why this isn't working for me.  The example I am given is:
> Find an estimate for the zero of the Polynomial.  f(x)=x^3-4x^2-2x+8
> 
> On a graph the estimated zero is between (1,2)   and it asks us to divide

> f[x_]:=x^3-4x^2-2x+8
> TableForm[Table[{i,f[i]},{i,1,2,0.1}],
> TableHeadings>{None,{"x","f(x)"}}]

> The > is as close as I can get to a right arrow sign
