12th Class Mathematics Continuity and Differentiability

    Answer:

    Being a polynomial function for x < 2 and x > 2, f is continuous.                         = 8 ? 3 = 5                         = 4 + 1 = 5       Also f(2) = 23 ? 3 = 8 ? 3 = 5       Since LHL = RHL = f(2)       Hence f is continuous and has no point of discontinuity.
