[CxvxzcvXcvxcv]

ok i have no damn clue what these damn questions are asking me can someone help me out? we are reading some passage and answering the questions but would be helpful if someone could help.

When an Oscilloscope input is dc coupled will the ac component of a displayed waveform be visible?
b) If ac coupling is selected on an oscilloscope and the dc offset setting on the function generator is changed, will there be any change to the displayed waveform.
c) If dc coupling is selected on an oscilloscope and the dc offset setting on the function generator is changed, will there be any change to the displayed waveform?

Yes. If it is displayed, it is visible by definition. That's what the word display implies.

b) no, although it may jump around initially.

c) yes, it will move vertically.
