Final answer:
The function f(x) = 4xΠ - 2x + 9 is a polynomial function (PF), because it consists of terms with powers of x and constant coefficients.
Step-by-step explanation:
The function given, f(x) = 4xΠ - 2x + 9, can be classified as a polynomial function which is typically denoted PF.
PF power function or EF exponential function is a one-term function where the exponent is a constant and the base is a variable. When a power function is involved, the exponent is always a real integer and a constant. A power function has the generic form f(x)=k.x increased to n.
Square root, cubic, linear, and quadratic functions are all included in the power function as long as they are single terms.
It is composed of terms that are either constants or powers of x with non-negative integer exponents. On the other hand, an exponential function, denoted EF, has a constant base raised to a power of x. Since the given function does not fit this description, it is not classified as an exponential function.
