Answer:

f(x) is defined in the interval [0, 10]       At x = 0             = 3 = f(0)       is continuous at x = 0       Now for x <1 and x >1       f(x) is a constant function       is continuous.       At x = 1                                      is discontinuous at x =1       Now for x < 3 and x > 3, f is again constant function and is continuous.       At x = 3                                                            is discontinuous at x = 3 also.       At x = 10                  is continuous at x =10.
