help me, please

The amplifier circuit below has a single ac input and two ac outputs. Assuming transistor
parameters of ß = 200 and VBE = 0.7 V:
Eth = 2.5V, Rth = 50kohm, Ic= 4.64mA, Vc- 3.47V, Ib 2.33uA, Vce = 1.67V, Ve = 1.8v
1. Based on the analysis results, what is the function of this circuit? Suggest a proper
application.
2. Assuming that each output is feeding a 100-k2 resistor, determine the total voltage gain
and current gain for both outputs. Also, calculate the amplifier input resistance and the
amplifier output resistances.
