Answer:

For x < 0 and x > 0        is continuous       [We know that, if g and h are continuous, then g/h, provided h(x)  is also continuous]       Here g(x) = |x| = modulus function and h(x) = x = polynomial function both are continuous function.       At x = 0                                      is discontinuous at x = 0.
