Chapter 5 Polynomials and Polynomial Functions - 5.2 Evaluate and Graph Polynomial Functions - 5.2 Exercises - Skill Practice - Page 341: 1

See answer below.

A polynomial function is in the form of $a_nx_n+a_{n-1}x_{n-1}+...+a_1x+a_0$ where $a_n\ne0$ and the coefficients are real. $a_n$ is the leading coefficient, $n$ is the degree, and the constant term is $a_0$. Hence here the function in standard form is: $-5x^4+2x^2+6$, which is a polynomial. Leading coefficient: $-5$ Degree: $4$ Quartic
