What is going on with the Operational amplifier?

In this case, the operational amplifier (UA741CP) is not working in buffer mode. I inquired as to why my circuit was not functioning properly. The question was answered (it will not work with these voltages), but it was also mentioned that everything is written in the UA741CP Datasheet. Could you please assist me in understanding the datasheet in the context of the given problem? I will specifically go over the additional information provided in the answer and highlight what I do not understand.

The schematic is:

Hi RachelAnne
I think your circuit will only work in the input voltage range of about 2 to 3 volts.
What is the input voltage range from volt to volt?
What exactly do you want to connect?
