Determine the values of a where the function f (x) is not continuous. Label each discontinuity as removable, jump or infinite. f(x) = {+2+7 -x+7 4 x ≤ 4 x>4 +4 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. x = (-infinity,4) continuous x= 4 continuous Please explain, in your own words and in a few sentences, how you arrived at your answers. Answers with no relevant explanations may receive reduced or no credit.
