In this paper we study extremal properties of functional associated with the half–linear second order differential equation E $_{p}$ . Necessary and sufficient condition for nonnegativity of this functional is given in two special cases: the first case is when both points are regular and the second is the case, when one end point is singular. The obtained results extend the theory of quadratic functionals.
