# Behavior of polynomial function

Start from second degree polynomials and then third degree...
Change the parameters a, b, c, d, and e many times to check the following
1) What are the general characteristics of polynomial functions (Domain, range, continuity...)
2) The zeros of polynomial functions (their number, relation to the degree...)
3) The number of maximum, minimums, turning points with respect to the degree
At the end answer the questions below

## Polynomial functions

## Domain

The domain of any polynomial function is?

## Continuity

Polynomial functions are continuous over

The range of third degree polynomial function is always

## Range

## Number of zeros(roots)

The number of real roots (the x-intercepts) of a second degree is (are)

## Number of zeros(roots)

The number of real roots (the x-intercepts) of a third degree is (are)

## Number of zeros(roots)

The number of real roots (the x-intercepts) of a fourth degree is (are)

## Number of turning points

The number of turning points (max-min) of a second degree polynomial is/are

## The number of turning points

The number of turning points (max-min) of a third degree polynomial is/are

## Number of turning points
