Question

Which description is correct for the polynomial 3x^3+4x^2−7?

Answer 1

A) cubic trinomial

Because the highest power is 3, it will be cubic.
1 = linear
2 = quadratic
3 = cubic
4 = bi quadratic

Because there are 3 terms, it is trinomial

3x^3
4x^2
-7

1 = monomial
2 = binomial
3 = trinomial
