Question
Hi there, please help me with answering this question. I am a bit confused here. The highlighted yellow squares labelled A and B are what I would like answered. The graphs that are boxed in blue are the correct graphs to reference, the first graph for part A and second for part B. Please read the question carefully because sometimes my questions are answered incorrectly and unfortunately I do not receive a refund for them. Please answer with legible handwriting as well. Thank you very much. Thumbs up always given for well explained answers!
