Determine the values of a where the function f (x) is not continuous. Label each discontinuity as removable, jump or infinite. X = x = Enter your answers as integers in increasing order. If there are no discontinuities, enter NA in both response areas and select continuous in both drop-down menus. If there is only one discontinuity, enter NA in the second response area and select continuous in the second drop-down menu. Click for List f(x) = = Click for List x- {} = +6 x + 3 x 3 x > 3
