2 0 / 3 points - - 2x Let f (ac) = ,x 7 2 2-2 4 ,= 2 Explain why the function is discontinuous at x = 2. Choose the one best answer. Of(2) is undefined. O limp +2- f(a) and lima +2+ f (ac) are finite, but are not equal. X O limz-+2 f(x) does not exist. Of(2) is defined and lima +2 f(a) is finite, but they are not equal
