Polynomial Functions

The general form of Polynomial Functions will be as the form.

$f(x)=a_{n}x^{n}+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}+....+a_{2}x^{2}+a_{1}x+a_{0}$

But need to remember that $a_{n}$ , $a_{n-1}$ ......$a_{1}$ and $a_{0}$ they can all be 0

The graph of Polynomial Functions can be looking as a U-shaped graph called a parabola.

One important feature of graphing the polynomial even functions graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph or the maximum value. In either case, the vertex is a turning point on the graph. The graph is also symmetric if you draw a vertical line drawn through the vertex, called the axis of symmetry.
