Find the x-values (if any) at which f(x)=x/x^2 -2x is not continuous.f(x) is not continuous at x=0 and f(x) has a removable discontinuity at x=0.f(x) is not continuous at x=0, 2 and both the discontinuities are nonremovable.f(x) is not continuous at x=2 and f(x) has a removable discontinuity at x=2.f(x) is not continuous at x=0,2 and f(x) has aremovable discontinuity at x=0.f(x) is continuous for all real x.
