State whether the function is a polynomial function or not. If it is, give its degree. If it is not, tell why not.
-$$f ( x ) = 1 + \frac { 7 } { x }$$
A) Yes; degree 7
B) Yes; degree 0
C) Yes; degree 1
D) No; x is raised to a negative power

Question

The function is not a polynomial because it contains $x$ raised to a negative power ($\frac{1}{x} = x^{-1}$). Polynomial functions only include terms where the variable is raised to a non-negative integer power.
