1. What is a function f from set A to set B, where
A = {1, 2, 3}
B = {x, y}
2. Let f : A -> B be a function from A to B.
f = {(w, 1), (x, 2), (y, 3), (z, 2)}
What is the domain of f?
3. Let f : A -> B be a function from A to B.
f = {(w, 1), (x, 2), (y, 3), (z, 2)}
What is the target of f?
4. Let f : A -> B be a function from A to B.
f = {(w, 1), (x, 2), (y, 3), (z, 2)}
What is the range of f (rng f)?
5. Let f: A ->B be a function from A to B
For any b ∈ B the equation b = f(x) has a solution x ∈ A.
