I plotted the points and everything but i don't know how to join them especially that my x axis starts from 0-10-20, so i don't know if i should extend the curve to 0 or not. Also after i extend it to 168, how can i make it decrease to 120??? Can u plz draw :)

Thanks in advance :D

PeaceMaker:
So, i got my Alternative to practicle paper coming up soon after the I.T exam. Wanted to say what we should focus on other than solving past papers? Of course solving gets you into the groove but knowing the meat of the paper (As in from which chapter they bring the questions from) is the most important thing. Or maybe notes for paper 6?

Thanks!
