Part 1: Write a complete proof of the equivalence of statements (1) and (2) in Theorem 4.11 of Croom.
Part 2: Next, write a complete proof of the following statement:
Let f, g: X→Yf, g: X→YY is Hausdorff and that there is a dense subset D of Xsuch that f(x)=g(x) for all x∈Dx∈D f(x)=g(x)f(x)=g(x) x∈Xx∈X

As with Writing Assignment #1, use a solid organizational structure:
– State the hypotheses
– State the conclusions
– Clearly and precisely prove the conclusions from the hypotheses
– Results presented earlier in the text may be used and must be clearly documented
A few notes about format: use Microsoft Word; use Equation Editor for all mathematical symbols, e.g. x ∈ X or Cl(A) ⋂ Cl(X-A); and use the fonts Cambria and Cambria Math in size 11 so your typed work is the same font as your equations.
