WebSolution : lim x-> x0- f(x) = f(x 0) (Because we have unfilled circle). But, lim x-> x0+ f(x) ≠ f(x 0) (Because we have filled circle at different place). Hence the given function is not continuous at the point x = x 0.. Question 2 : … WebSolution : (i) First let us check whether the piece wise function is continuous at x = 0. For the values of x lesser than 0, we have to select the function f (x) = 0. lim x->0- f (x) = lim x->0 - 0. = 0 ------- (1) For the …
