Third-degree
Polynomial
1) Considering the polynomial expression we can rewrite it:
[tex]\begin{gathered} 14.8-1.379t+0.451t^2-0.012t^3 \\ -0.012t^3+0.451t^2-1.379t+14.8 \end{gathered}[/tex]So now we can visualize it better we can state: this is a third-degree polynomial since the leading coefficient is raised to the 3rd. degree.
2) As this polynomial has 4 terms then we can call it a polynomial.
3) Hence, the answer is:
Third degree
