its not connected to output voltage

So you have a poll that asks if the op amp is an op amp or an op amp.

Good luck on getting any useful information from your poll.

As for the question posted in the screenshot, what is the output of an op amp in terms of the input voltages, taking into account the limits imposed by the supply voltages?

Or are you just looking for someone to give you the answer?

Q1.
Can you tell me the voltages that are used to power the op amp?
(Clue 1: there are two of them, so your answer must contain two voltages)
(Clue 2: in some places these voltages are called rails, they provide the upper and lower boundaries (rails) for the output, the output can not exceed the upper boundary (rail) and the output can not go lower than the bottom boundary (rail))

Sorry for that I am new at here so i didn't know how the pole works i want to know what type of op amp is it.

Since no specifics are given, you have little choice but to assume that it is an ideal op amp.

In order to determine the output of the circuit of which this op amp is a part of, you just need to know what the output of an op amp is as a function of the voltages at its two input pins.

What is that relationship? If you don't know, then look it up.

It's "poll", not "pole". Look up both words to learn the difference.

You shouldn't need to look up what a comparator circuit is or what it does. You have an op amp circuit that is very easy to analyze simply by understanding the fundamental concept of an opamp as being a very high gain differential amplifier.

Sorry William, I recognize how much the regulars do to help.

I should have refrained to post that. Not the best qualified to judge, much less to preach them.

Oh, no problem at all. I waffled a bit on being that explicit, but finally opted to go ahead and be so. Judgment call.
