5. Let f(x)= 1/q. if r Q and x = p/q in lowest terms, if r is irrational. 0. Note that the set of the points where f is discontinuous is Q. (a). Use Lebesgue's Theorem to determine if f is Riemann integrable on [a, b]. (b). Use Riemann's Lemma to determine if f is Riemann integrable on [a, b]. (c). Evaluate [₁ f(x)dx if it exists.
