Graph f, locate all points of discontinuity, and discuss the behavior of f at these points. -1+x ifxs -1 1 ( x ) = -3-x ifx> - 1 Locate all points of discontinuity. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The point(s) of discontinuity is/are x = (Use a comma to separate answers as needed.) B. There are no points of discontinuity. Discuss the behavior of f at its point(s) of discontinuity. Find f(x) at any points of discontinuity. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The point(s) of discontinuity defined by f(x) have the value(s) . All other points of discontinuity are not defined by f(x). (Use a comma to separate answers as needed.) O B. The point(s) of discontinuity are not defined by f(x). O C. There are no points of discontinuity
