Can anybody answer this hard question Function of x bracket 1 if X is a rational number or 0 if X is an Irrational number?
Nintendors
f(x) = 1 if x is rational
f(x) = 0 if x is irrational
But there is no specific question about this function. It is a well defined function whose domain is the real numbers and whose codomain consists of the two values, 0 and 1.
It is a function with infinitely many discontinuities, and an integral which is 0.

Numbers confuse me and always have since grade school when my teacher used to beat me for getting my numbers mixed up. I guess that feeling has stuck with me.
