----- Original Message ----- Is this a homework problem? I assume it is not. I found no difficulty in displaying your table (perhaps you have some punctuation problem): In[1]:= Clear[f]; f[x_] := x^3 - 4*x^2 - 2*x + 8 In[2]:= TableForm[Table[{i, f[i]}, {i, 1, 2, 0.1}], TableHeadings -> {None, {"x", "f(x)"}}] (I omit the output). It displays all right. I don't understand what you say about the right arrow sign.
