Function (mathematics)/Polynomial Function

Polynomial Function
function of a power of variable x that has a general form
 * $$A_n x^n + A_{n-1} x^{n-1} + ... + A_1 x+ A_o x^0$$

For example
 * First ordered polynomial function . $$Ax+B $$
 * Second ordered polynomial function  . $$Ax^2+Bx+C $$
 * nth ordered polynomial function . $$A_n x^n + A_{n-1} x^{n-1} + ... + A_1 x+ A_o x^0$$

1st ordered polynomial function

 * $$y = x$$
 * x | -3 -2 -1 0 1 2 3
 * y | -3 -2 -1 0 1 2 3
 * Straight line goes through origin (0,0) has slope $$1$$


 * $$y = 3x$$
 * x | -3 -2 -1 0 1 2 3
 * y | -9 -6 -3 0 3 6 9
 * Straight line goes through origin (0,0) has slope $$3$$


 * $$y = 3x+1$$
 * x | -3 -2 -1 0 1 2 3
 * y | -9 -6 -3 0 3 6 10
 * Straight line goes through origin (0,0) has slope $$3$$ and shift upward 1 unit
