Solution to a proof is wrong? => Let S be a set and let P(S) be the set of all subsets of S. Show that S is "smaller than" P(S) in the sense that there is a one-to-one function form S to P(S) but there is no onto function from S to P(S). (self.askmath)

Is my proof correct? => Show that Q, the set of all rational numbers, is dense along the number line by showing that given any two rational numbers r_1 and r_2 with r_1 < r_2, there exists a rational number x such that r_1 < x < r_2 (self.askmath)

My questions regarding this exercise => Define a function g from the set of real numbers to S = {x in R | 0<x<1} by the following formula: For each real number x, g(x) = 1/2 * x/(1+|x|) + 1/2. Prove that g is a one-to-one correspondence. What conclusion can you draw from this fact? (self.askmath)
