Select the correct statement. The function f (x ) = x-x-6 x-3 O has a removable discontinuity at x = 3. O is continuous on (-0o, co). O has a jump discontinuity at a = 3. O has a vertical asymptote at x = 3. O is continuous from the left at x = 3. O is continuous from the right at a = 3. O is continuous on (-oo, oo ) if we define f (3) = 0. O has the limit limx-+3 f (a) = -5
