A polynomial function is a function in the form:

$\bullet$leading coefficient: "${a_n}$", the coefficient of the highest power of x

$\bullet$constant term: "${a_0}$", the term without $x$

$\bullet$degree of the polynomial function: $n$, the highest power of $x$

- IntroductionIntroduction to Polynomial Functions

$\cdot$ What is a polynomial function?

$\cdot$ Exercise:

State the*degree, leading coefficient*and*constant term*for the following polynomial functions:

1) $f(x) = 9x^{5}+7x^{4}-2x^{3}-12x^{2}+x-10$

2) $p(x) = -23x^{18}+37x^{15}-11x^{58}+6$ - 1.
**Recognizing a Polynomial Function**Which of the following are not polynomial functions? Explain.

a)$f(x) = 5x^{2}+4x-3x^{-1}+2$b)$f(x) = -x^{3}+6x^{\frac{1}{2}}$c)$f(x) = (\sqrt x + 3)(\sqrt x - 3)$d)$f(x) = x^{5}+\pi x-\sqrt7 x^{2}+\frac{3}{11}$ - 2.
