Question

2.

Classify by degree of polynomial:
7x3 - 8x2 -4x+ 9
a) Constant
b) Linear
d) Cubic
c) Quadratic

Answer 1

D/C, Cubic

Explanation:

7x^3 is the highest degree term. 3 is highest degree. Anything with a 3rd degree is called a cubic polynomial (think something cubed is raised to the third power). Therefore, the answer is cubic. It says, D, cubic, but it is the third answer.
