12th Class Mathematics Continuity and Differentiability

  • question_answer 9)  


    For x< 0, f(x)  is continuous and for x > 0, f(x) is a constant function and therefore continuous.       At x = 0                               Also f(0) = ?1       Since LHL = RHL = f(0)       Therefore f is continuous function       Hence f has no point of discontinuous.
