In this course its important to know the standard forms of each graph. I had a huge problem in solving inequalities and also understanding and answering cubic graphs , so chapter 4&5 really explained that in depth. This course also eased knowing how to plot the axes, turning points etc of a cubic graph because wow.

Wow I can't believe I've finally completed this course. I always didn't really like functions from amongst the other topics in maths and this course really helped to change that. I definitely would recommend it to anyone who feels a bit shaky when it comes to a topic like this.
