Question 983324: determine whether function is a polynomial function , if it is, state the degree, if it is not, tell why.......f(x)=3x+x^-9
polynomial degree of 3
polynomial degree of -9
not polynomial ... negative coefficient of x
not polynomial ....negative power of x

It is D
not a polynomial because a polynomial doesn't allow division by a variable, and x^-9 is 1/x^9.
The coefficient can be positive or negative.
