Hi Ryan, just checking, for part (ii) shouldn't the graph start at t=0? How did the years become negative 2.5? Please explain. Shouldn't the graph be drawn from t=0 to t=10 years?

Hi. Dileep. Sorry. Reply you after one year. For (ii), I think, if there is no special condition, the years can be negative which is purely matched with the equation. As long as it is a full cycle, I think it should be right. But 0-10 years of course is right.
