You will also get the detailed steps and explanations for the solution. This is a part of Chapter 2 Class 12 Inverse Trigonometric Functions.Solution. The function f (x) = 1 u2 +u−2 suffers a discontinuity at the points where u2 +u−2 =0 i.e., u =−2 and u = 1. Using these value of u, the corresponding values of x are obtained by solving the equations. Hence, the composite function is discontinuous at three points x = 1 2,x = 1 and x = 2.
