Is the function f defined by  continuous at x = 0? At x = 1?  

Answer:

. At x = 0             Also f(0) = 0       Since        is continuous at x = 0       At x = 1                               Since        is discontinuous at x = 1.       At x = 2             Also f(2) = 5                  Since        is continuous at x = 2.       Find all the points of discontinuity of f defined by :
