\$\begingroup\$ Consider the circuit neglecting R1 and the lower op-amp: that's a differential amplifier and it's characterized by a certain transfer function. Consider the remaining op-amp only in its configuration: that's a voltage follower. Now, the follower drives a branch of the differential amp and in turn it's driven by the differential amp through a resistor.
