Determine if $$f ( x ) = 2 x ^ { 3 } + 2 x ^ { 2 } - \frac { 1 } { x }$$ is a polynomial function. If it is, state the degree and the leading coefficient. If not, state why not. Yes. The degree is $$2$$ and the leading coefficient is $$3$$ . No. There is an exponent on a variable x that is not a whole number. Yes. The degree is $$3$$ and the leading coefficient is $$2$$ . No. The leading coefficient is not a whole number.
