Which answer describes the polynomial? 3x^3 + 4x^2 - 7 a) quartic trinomial b) cubic trinomial c) quadratic trinomial d) cubic binomial

Because there are three terms in this polynomial function, this would be considered a trinomial. Knowing that, we can immediately eliminate choice D.

Look at the highest degree in the problem and identify it. The degree should be 3. This means that the function is cubic. So, the best choice is B) Cubic Trinomial.

**For future reference, know that quartic is an unknown quantity or variable to the fourth power. While a quadratic is an unknown quantity or variable to the second power.

The answer would be -3.9> -4.5
