Homework Statement Give an example of a function whose domain equals the interval (0,1) but whose range is equal to [0, 1]. 2. The attempt at a solution I can't see a way how such function would exits. I though about it this way, if it was the opposite Domain [0,1] and range (0, 1), we could...

You are right in doesn't necessarily state that all they are not equal in terms of irrational numbers in their domain

Homework Statement Given an example of two different functions f and g, both of which have the set of real numbers as their domain, such that f(x)=g(x) for every rational number. 2. The attempt at a solution I have yet to figure a way to approach this problem. Since it appears as...
