1.	Let f(x) = sgn (x) and g (x) = `x(x^(2)-5x+6)`. The function f(g(x)) is discontinuous atA. Infinitely many pointsB. Exactly one pointC. Exactly three pointsD. No point
Answer» Correct Answer - C `becauseg(x)` is continuous is R and f(x) is discontinuouse at x = 0. `therefore f{g(x)}` is discontinuous at the points where g (x) =0 OR at x = 0,2,3.
