f(x)=1q if x=pq where p and q are integer and q≠0, G.C.D of (p, q) – InterviewSolution

1.	f(x)=1q if x=pq where p and q are integer and q≠0, G.C.D of (p, q) = 1 and f(x) = 0 if x is irrational then set of continuous points of f(x) is
Answer» $f (x) = \frac{1}{q}$ if $x = \frac{p}{q}$ where p and q are integer and $q \neq 0$ , G.C.D of (p, q) = 1 and f(x) = 0 if x is irrational then set of continuous points of f(x) is
