Question 356763
the function f(x) = 0 * x will always yield an answer of 0.


the function of f(x) = x^0 will always yield an answer of 1.


the function of f(x) = 0 / anything will always yield an answer of 0.


the function of f(x) = anything / 0 will always yield an answer of infinity.


since infinity is undefined, the answer will always be undefined.


the function of f(x) = x/x will always yield an answer of 1.


these are the most common that i know of.
