  1. On the same axes, sketch the graphs of \(y = -\frac{b}{x-a}\) and \(y = |x-a|\), where \(a\) and \(b\) are positive constants and \(a > b > 1\). State, in terms of \(a\) and \(b\), the coordinates of the points where the curves cross the \(x\)- and \(y\)- axes.[3]
  2. Hence or otherwise, solve the inequality \(-\frac{b}{x-a} < |x-a|\).[4]
