For the first question, I think it might be A or D but I'm not sure. The second one I think is A but I'm probably wrong because I'm not very good with the rate of change. The last one, I have no idea what the answer could be. Maybe D? Help me please because I really need to understand these. Sorry. Thank you. Also, the pictures won't stay small so sorry for them being big. Tried changing them three times.
