Let T be a piecewise continuously differentiable mapping of an interval \([a,b]\) into itself. The author gives conditions under which there is a non-singular conjugation of T with a piecewise expanding mapping. The results are then applied to the family of mappings \(T_ ax=ax(1-x)\) of the unit interval into itself. It is shown that there is a continuum of values of the parameter a for which \(T_ a\) is non-singularly conjugate to a piecewise expanding mapping.
