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}
