CBSE Class 12-science Answered

show that the function defined by g(x)=x- [x] is discontinuous at all
Asked by | 27 Aug, 2008, 12:30: PM
Expert Answer

this function is discontinuous at all integer points

let a be a integer so when x<a- then [x] = a-1 and f(x) = 1

but when x= a+ then [x] = a and f(x) = 0

so f(a - ) is not equal to f( a+)

so function is discontinuous at all integers.
