7. Refer to the following graph of f(x). a. At what value(s) of x is f(x) discontinuous? D X- -3 oxz - 1 U X = 2 b. Determine whether the limit of f(x) exists (both one-sided and the limit) at each value given in part a. X = 13 lim . lim lim X2+ = 1.3 Ya- =-0.5 lim =.0.5 *+ - 3" x -3 Does Not lim X - > - 1 1 = 1.3 exist I im x -2 = Under cred C. Classify any points of discontinuity as either removable or nonremovable. 0.5 -3 0.5 O -1 -1.5 C . at y= 2 the discontinuity is removable at x = - 3 3 x = -1 the discontinuity Is not removable
