Not gonna screw up my advance function! :D

As I said in the previous post, I encounter problems when come to solve the some of the questions in chapter 5. Thus, I take initiative to learn through Youtube (that's what a teenager living in the advance technology era should do, make good use of the internet :D). 

And I find a number of nice and kind-heart beings upload their tutorial videos in different topics of Maths to Youtube and fellows viewers just watch for free and benefited from them.(A round of applause for them!) Some of the videos are indeed useful and I really would like to share them with you all who face the same difficulty as me, sharing is caring, right right:D

Appreciate the good job done by MathTv. 

Here comes the complicated part! How to graph a transformed graph.
