Mark the correct alternative in the following:

Let Then, f(x) is continuous on the set


Formula:-


(i) A function f(x) is said to be continuous at a point x=a of its domain, iff



Given:-



Using R.H.L at x=1




Using L.H.L at x=1




And Using R.H.L at x=2



Using L.H.L at x=2



F(x) is discontinuous at x=1 and x=2


For f(x) continuous at R-{1,2}
