Some Fejér-Type Inequalities for Generalized Interval-Valued Convex Functions

The goal of this study is to create new variations the well-known Hermite–Hadamard inequality (HH-inequality) for preinvex interval-valued functions (preinvex I-V-Fs). We develop several additional inequalities class whose product I-V-Fs. findings described here would be generalizations those found in previous studies. Finally, we obtain Hermite–Hadamard–Fejér with support functions. Some and classical special cases are also obtained. Moreover, some nontrivial examples given check validity our main results.
