This was the video. God bless man and hope you still teaching.

I’m reviewing all the lessons in Math. Was looking for an explanation about composite function, found this. Looked at the time… uploaded 6 mins ago. Your videos are amazing!

U don't understand how much u are helping slow students like me 😭👍🏼

It’s easy to find…it’s right there. Knowing what to do with it, however, is the real puzzle.

Good basic example. I would like to see domains mentioned though. Here f and g have domain R. But, make f(x)=1/x and g(x)=sin(x). Slightly different input domains, very different output domaine (R\{k * pi} with k element Z.

Haters gonna hate but stay strong you are the reason i am passing math class

Thank you, thank you, thank you!!! 😁

What about the reversed problem as followed?
f(g(x)) and g(x) are given, find f(x)??

Nemo_Doko

I'm still confused. How do you determine that g(x) =x+1? Either f or x is a variable at this time. You don't know the value of either? You could say x*1 correctly but I don't understand how you can say x+1????

Mathematics is only a way of mapping. Just like a measuring tape it doesn't even exist only if you agree and utilize this technique otherwise there's much better application much more advanced you have no idea

MrHailteam

That's actually quite bizarre based on certain assumptions based on zero facts

MrHailteam

i hate just using youtube this is miserable

Back in the Stone age they didn't use this primitive technique of mathematics.. if you want to learn advanced mathematics skills call me
