Determine if ƒ(x) = 3x2 – 2x3 – x – 9 is a polynomial function. if it is, state the degree and the leading coefficient. if not, state why.

This is indeed a polymomial, it's just not in the correct order.  The term with the highest exponent goes first, dictating the degree of the whole entire polynomial.  In descending order, the polynomial is written correctly as .  It is a third degree polynomial with a leading coefficient of -2. 

The correct answer is 7
