Web1) Let f(x) = 1 if xis rational and f(x) = 0 if xis irrational. Show that f is not continuous at any real number. Solution Fix any x 2R. We will show that f is not continuous at x. We work by contradiction. Assume f is continuous at x. Then there exists > 0 such that for all y2R with jy xj< , jf(y) f(x)j<1. This means that for any y2(x ;x+ ), WebQ: Sx², lo, (0, x is irrational. x is rational Let f(x) Show that f is differentiable at x = 0.
