comment continuity of the Thomae function
@DavidMitra: Thanks. I am asking because, the above facts were asked in the same question that asked to show that $t(x)$ has the stated properties. Showing that $t(x)$ is continuous at the irrationals is bit daunting I think.

comment continuity of the Thomae function
@DavidMitra: Since $\mathbb Q$ is an $F_\sigma$ and the set of discontinuities of any function is an $F_\sigma$ set, can't I say that $t(x)$ is discontinuous at the rationals?
