WebMay 11, 2016 · (1) f − 1 ( ( c, ∞)) = [ f − 1 ( ( c, ∞)) ∩ E] ∪ [ f − 1 ( ( c, ∞)) ∩ D]. Because f is continuous on E, the first set on the right of ( 1) is open in E. Thus it equals E ∩ U for some U open in R. Because E, U are both measurable, so is f − 1 ( ( c, ∞)) ∩ E. And because m ( D) = 0, any subset of D is measurable.
