Transform the data along with the model back to the original form. The degree of a polynomial function is the highest power of the variable that occurs in a polynomial. Because of the end behavior, we know that the lead coefficient must be negative. Because of the form of a polynomial function, we can see an infinite variety in the number of terms and the power of the variable. For these odd power functions, as \(x\) approaches negative infinity, \(f(x)\) decreases without bound. The degree is even (4) and the leading coefficient is negative (3), so the end behavior is, \[\text{as }x{\rightarrow}{\infty}, \; f(x){\rightarrow}{\infty} \nonumber\], \[\text{as } x{\rightarrow}{\infty}, \; f(x){\rightarrow}{\infty} \nonumber\].
