a) use the sequential definition of continuity to prove that f(x)=|x| is continuous. b) theorem 17.3 states that if f is continuous at x0, then |f| is continuous at x0. is the converse true? if so, prove it. if not find a counterexample. hint: use counterexample

Let (X,dX),(Y,dY ) be metric spaces and f: X → Y be a continuous bijection. Prove that if (X, dX ) is compact, then f is a homeomorphism. (Hint: it might be convenient to use that a function is continuous if and only if the inverse image of every open set is open, if and only if the inverse image of every closed set is closed).

Differential Geometry (Mixed Use of Vector Calculus & Linear Algebra) 1A. Prove that if p=(x,y) is in the set where y<x and if r=distance from p to the line y=x then the ball about p of radius r does not intersect with the line y=x. 1B. Prove that the set where y<c is an open set.

Proof of If and Only if (IFF) and Contrapositive Let x,y be integers. Prove that the...

Proof of If and Only if (IFF) and Contrapositive Let x,y be integers. Prove that the product xy is odd if and only if x and y are both odd integers. Proof by Contradiction Use proof by contradiction to show that the difference of any irrational number and any rational number is irrational. In other words, prove that if a is irrational and b is a rational numbers, then a−b is irrational. Direct Proof Using a direct proof, prove that:...
