The output of NOT gate ( left part of the circuit) is the input of the NOR gate 

Hence the output of total circuit Y = \over(\overline A + \overline B) 

                                                 =  \overline{\overline A}.\overline{\overline B}                                  \overline{A+B}=\overline A. \overline B

                                                  = A*B

Hence the circuit functions as AND gate.

or give the inputs 00,01,10,11 and observe the truth table

 

INPUTS

 

OUTPUT
A        B Y
0         0 0
0         1 0
1         0 0
1         1 1

The truth table is the same as that of AND gate
