You can put this solution on YOUR website!
a) it's a trinomial --- True, there are 3 monomial terms.

b)it can not be evaluated at x=-1/3 --- False, it can be evaluated at x = -1/3 (doing so gives you 158/27)

c)it has a coefficient of 8 --- False, it has a coefficient of -8 but not 8.

d) it is a cubic --- True, 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)
