Question

Is `f(x)=x^3-11x^2+3^x` a polynomial?

Answer 1

No, it is not a polynomial function.

Explanation:

Although `x^3-11x^2` is a polynomial, the term `3^x` is not of a form that we include in polynomials.

Terms of a polynomial must be either a constant (a number), or a constant times a variable raised to a positive integer power.
