Ok, quick tip: for both Mark's and Leo's fishing rods, add the data point (0,0). Since the 1st guide is the 1st guide from the tip, guide number 0 is the tip, which obviously must have a distance of 0cm from the tip. Then, basically, try to find polynomial functions that best fit your data points. Remember to discuss your choices; even though a sextic function will fit all the data points, it's probably not the right choice. Probably a quadratic function will be the best.

No. I'm sorry, but we can't help you with solving questions in the portfolio, it's against IBO regulation and it's morally wrong towards those (including me) who do their portfolio by themselves.
