If `f(x)=|x-1|-[x]`, where `[x]` is the greatest integer less than or equal to x, thenA. `underset(xto0)lim[f(x)]=0`B. `underset(xto0)lim[f(x)]=1`C. `underset(xto0)lim[(f(x))/(x)]` does not existD. `underset(xto0)lim[(f(x))/(x)]` exists

Answer» Correct Answer - A::D
`f(1+0)=underset(hto0)lim(|1+h-1|-[1+h])=underset(hto0)lim(h-1)=-1`
`f(1-0)=underset(hto0)lim(|1-h-1|-[1-h])=underset(hto0)lim(h-0)=0`
