good day guys. i just found the circuit that I can use for my report but the problem is I'm am struggling finding the input and output impedance of this circuit. can someone help me?

I agree with Dick. They've just been drawn upside down.Its input transistors are wrongly PNP
Looks much better now.Assume the schematic was corrected; What is the input impedance? Start at the input and you have C1 & R1. That gets you close to the right answer. Ony because this is a school project, you should go beyond that and find the answer is slightly lower than that. So agentperry15 please tell us what is the input impedance?

thank you for your answers guys. but still don't know to calculate this properly. do you have any circuit that has 25 watts output power composed only with transistor?
