8 Homework Due Friday Apr 3 1. (Ch 4, Question 7.) If E X and if f is a function defined on X, the restriction of f to E is the function h whose domain is E and h(p) = f (p) for p E. Define f, g : R2 R by 0 if (x, y) = (0, 0) f (x, y) = xy 2 if (x, y) = (0, 0) (x2 +y 4 ) g(x, y) = 0 xy 2 (x2 +y 6 ) if (x, y) = (0, 0) if (x, y) = (0, 0) Prove that f is bounded on R2 (Hint: consider (x - y 2 )2 ), g is unbounded in every neighbourhood of (0, 0) and that f is not continuous at (0, 0). Prove however that the restrictions of both f and g to any straight line in R2 are continuous. (Ch 2. 4, Question 1.) Suppose f : R R satisfies h0 lim [f (x + h) - f (x - h)] = 0 for each x R. Does this imply that f is continuous? 3. (Ch 4, Question 2.) If f : X Y is continuous prove that f (E) f (E) for every E X. Show, by an example, that f (E) can be a proper subset of f (E). 4. (Ch 4, Question 3.) Let f : X R where X is a metric space and f is continuous. Let Z(f ) (the zero set of f ) be {x X | f (x) = 0}. Prove that Z(f ) is closed. 5. (Ch 4, Question 8.) Let E be a bounded subset of R and f : E R be uniformly continuous on E. Show that f (E) is bounded.
