Suppose that A is the set of sophomores at your school and B is the set of students in discrete mathematics at your school. Express each of these sets in terms of A and B.

a) the set of sophomores taking discrete mathematics in your school

b) the set of sophomores at your school who are not taking discrete mathematics

c) the set of students at your school who either are sophomores or are taking discrete mathematics

Use these symbols:$\cap \cup$

Prove based on functions

Prove that for all $f,g\in \mathbb{N}\to \{0,1\}$ there exist $h\in \mathbb{N}\to \mathbb{N}$ bijection so:

$f=g\circ h\to f=g$

My attempt was to assume that for all $f,g\in \mathbb{N}\to \{0,1\}$ there exist $h\in \mathbb{N}\to \mathbb{N}$ bijection so: $f=g\circ h\wedge f\ne g$ and try to get a contradiction without any succed.
