Answer
Type: Polynomial
Terms: x, -$x^2$, $x^3$, -$x^4$
Degree: 4
Work Step by Step
The type of the monomial is a monomial if it has one term, a binomial if it has two terms, and a trinomial if it has three terms. This polynomial has 4 terms, therefore it is not referred to by any of these terms and is simply called a four term polynomial. The terms are simply the values separated by plus and minus signs: x, -$x^2$, $x^3$, -$x^4$. The degree is just the highest exponent of the variable in any of the terms, and if no x is present, the degree is 0. Therefore, the degree of this polynomial is 4.
