1.6 common functions and their graphs
(1) Polynomials
There are many functions that are established with the non-negative power of x. The general formula of polynomials is:
The coefficient of 
is the coefficient of the entire polynomial. The n here is called the degree of the polynomial. The graphs of polynomials are really simple to recognize, like the picture below.
However, many graphs of polynomials are really hard to draw, because sometimes its even impossible to find the intercept. But the trend of the two sides is easy to figure out. Please look at the picture below:
n is even and n is odd and n is even and n is odd and
