Question 1058688: Decide whether h(x)=−3x2+2x−9+4√x3
is a polynomial function.
polynomial function**
not a polynomial function
If the function is a polynomial function, write it in standard form and state its degree, type, and leading coefficient. If not, leave each response blank.
h(x)=?

State the degree, type, and leading coefficient of the function.
degree: 3
type: cubic
leading coefficient: 2

It is not a polynomial function, because the definition of a polynomial function has non-negative integer powers of x. If it is supposed to be a polynomial function, then what appears to be to me a square root of x^3 must be rewritten, for as it stands, it is x^3/2, which while x and x^(1/2) still doesn't fit the definition.
Were it 3x^2+2x-9+4x^3 then it would be.
