How many constants can a polynomial have?

A polynomial can have:
constants (like 3, −20, or ½)variables (like x and y)exponents (like the 2 in y2), but only 0, 1, 2, 3, ... etc are allowedthat can be combined using addition, subtraction, multiplication and division ...
... except ...
... not division by a variable (so something like 2/x is right out)

HOPES THIS INFORMATION HELPS

f(x) = (x-1)^2 -2

Step-by-step explanation:

It is the toolkit function f(x)= x^2 which center would traditionally be at (0,0) In this case you see that it is moved down by two units so that is represented by the (-2). If you look you can see it is moved to the right by  1 unit but it is not +1 like you would think, it is -1 for whatver reason ... that is just the rule. This goes next to the x. Hence f(x)=(x-1)^2 -2
