Hi Eddie, I am 70 and finally have time to improve my maths. Would you be able to put a list up on your channnel or somewhere of videos in order of difficulty...or in groups in order of difficulty. As I am not familiar with current curriculum names I am unsure of where to start and continue. Thanks

This is AMAZING hands down. The way you teach makes it so interesting.

I love you, dont stop! This helps me a lot ghost teach pretending to have your enthusiasm and public speaking. what program are you using to display the functions? Desmos?

Dude I love your approach to teaching maths, am in Ireland, only half a year of Secondary school left, from tomorrow my Pre-Leaving Certificate exams are starting, and in June my actual Leaving Cert, and I’ve always had a problem with my maths teachers(not just the fact that my teacher just went on maternity... and am left with a relatively bad one) but their style of teaching is dreadful, you put some enthusiasm in there making it more interesting, what Grade do you teach or do you teach multiple? I’m a 6th year( age 17, and some people in the year are 18 so I dunno the equivalent)

What is that website to graph functions?

Hi,

I am very confused with order of transformations when graphing. I have two questions below which seem contradictory in terms of the answer for reflections in y and dilation from y:

Question 1:
The graph of g(x) = x^2 undergoes the following transformations:
• reflection in the y-axis
• translation 4 units right
• dilation of factor 2 from the y-axis
• translation 3 units down
• dilation of factor 1/3 from the x-axis.
Find the rule of the image of the graph.

Question 2:
The graph of h(x) = 1/x undergoes the following transformations:
• dilation of factor 3 parallel to the x-axis
• translation 2 units up
• reflection in the y-axis
• translation 1 unit left
• reflection in the x-axis.
Find the rule of the image of the graph.

What confuses me is the reflection in y and the dilation in x. Can someone please walk me through the solution for each question?

Thanks!!

I also recommend GeoGebra, it does something similar. Great explanation Mr Woo, thanks! :3
