Nice video. Thank y8u for sharing.
You forgot the 'plus and minus' when you took the squareroot, when finding the first inverse function (which does actually not exits when the domain is R) 😉

great video, but don't forget when you square root (in example of h(24)=sqr(24+1) it becomes + or - 5 not just 5 :) ) My teacher always shouts at me for that :D

Thx you! But I think you may add a domain to inverse h(x).
