Hi, would like to comment that on the portion of representing functions, I learnt that [ means "inclusive" and ( means "non-inclusive"

you said in the video that [ means "non inclusive" while ( means "inclusive". Just smth to note, thanks! :D

at 1:34:37 shouldn't λ be -8? if we sub λ = 8 into f(x), the turning point will be on the right of the y-axis, meaning that it is still many-to-one if the domain is x > 0. However subbing λ = -8, the turning point is to the left of the y-axis, so for the domain x > 0, it will be a one-to-one function.
