Question 597765
a) it's a trinomial --- <font color="red">True</font>, there are 3 monomial terms.


b)it can not be evaluated at x=-1/3 --- <font color="red">False</font>, it can be evaluated at x = -1/3 (doing so gives you 158/27)


c)it has a coefficient of 8 --- <font color="red">False</font>, it has a coefficient of -8 but not 8.


d) it is a cubic --- <font color="red">True</font>, the term with the largest exponent over the variable is x^3, which means that this is a 3rd degree polynomial (and that it's a cubic)
