May 9, 2022 · A(w) = 576π + 384πw + 64πw2. This formula is an example of a polynomial function. A polynomial function consists of either zero or the sum of a finite number of non-zero terms, each of which is a product of a number, called the coefficient of the term, and a variable raised to a non-negative integer power.

Oct 31, 2021 · h(x) = 5√x + 2. Solution. The first two functions are examples of polynomial functions because they can be written in the form of Equation 3.3.2, where the powers are non-negative integers and the coefficients are real numbers. f(x) can be written as f(x) = 6x4 + 4. g(x) can be written as g(x) = − x3 + 4x.
