Consider the class of prequasiinvex functions. In this paper, some characterizations of prequasiinvex function are provided. Under prequasiinvexity conditions, determination of the satisfaction of semistrictly prequasiinvexity for a function can be achieved via an intermediate-point semistrictly prequasiinvexity check.
