Polynomial: An algebraic expression consisting of variables and coefficients combined using addition, subtraction, and multiplication. In this case, our given function is a polynomial.
Degree: The highest power of x in a polynomial. In this case, the degree of our given function is 3 since the highest power of x is 3.
Coefficients: The constant values multiplied by each term's variable. For example, in the term -2x^2, -2 is the coefficient.
