  • question_answer
    Number of points of discontinuity of \[|\{x\}|+\sqrt{\{x\}}\] in the interval (-2, are (where [.] is GIF and {.} is fractional part of x)

    A)  0                            

    B)  2      

    C)  3                            

    D)  1

    Correct Answer: B

    Solution :

    As GIF and fractional part function are discontinuous at integral value of x, so only possibility can by -1, 0, 1. On checking LHL & RHL except x = 1 all are discontinuous.
