Here, THE Input = A and B 

Output = Y 

The left part of the figure acts as a NOR and right part acts as NOT Gate.

The output of NOR gate =  \overline{A+B} 

the output  of the NOR gate would be the input of NOT Gate and hence 

                        Y = \over\overline{A+B} = \overline\overline{A+B}

Hence the figure functions like an OR Gate.

or compare the truth table by giving different input and observing the output
