Polynomial function is usually represented in the following way: a n k n + a n-1 k n-1 +.+a 2 k 2 + a 1 k + a 0, then for k 0 or k 0, P(k) a n k n. Hence, the polynomial functions reach power functions for the largest values of their variables. When n is negative, the value of a function is inversely proportional to the {eq}n^\text{th}{/eq} power of {eq}x{/eq}.Here are some power functions: {eq}-7x^2, 3\sqrt{n}, \frac{5}{p^3} , 78z^{12}.
