    In under the first two minutes of this video, it feels like all my worries are gone, all my problems are solved and my brain is at ease. Very well explained, THANK. YOU. Especially during this pandemic where many of us don't have teachers by our side, thank goodness we have you to explain to us. Have a nice day/night!

    That's funny. I was dreading how difficult composite and inverse functions were moments ago until this video appeared in my recommendations. How convenient lol.

    When you teach,forget the all idea of students knowing a thing or more about what you are about to teach.Teach like it's the first time that thing is being heard of on earth and then you will be one of the greatest tutors ever.

  • @zebulon39u
    @zebulon39u 4 ปีที่แล้ว +9

    I've watched quite a few videos on how to find inverse functions and they all use the "y" substitution method, but this is the best one because the presenter actually takes a moment to explain what is going on and the theory behind it.

    For the first time, I finally understood what youtube video taught me. I usually puzzled by the comments of many other video claiming it saves their life and how easy it is to understood while the content of it was hard to digest which I suspect that those that dont understand simply didnt comment about it but this video is different, I can finally understands it. Many thanks, this will helps my final of this semester.

    Do not use the symbolism fg(x) but the right is f(g(x)). We must avoid confusion with multiplication.
