$8x^4+6x-3$

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; $n$ is non-negative integer. $a_n$ is the leading coefficient, and $n$ is the degree. Hence here the function in standard form is: $8x^4+6x-3$, which is a polynomial. Leading coefficient: $8$ Degree: $4$ Quartic
