Intro to Inverse Functions (4 of 4: Worked example)

[@anniquelezama1951]

This is soooooo helpful thanks dude. Keep killin it

[@tomharrysson8379]

Thanks that was very well explained

[@danattack4779]

I would have to go step by step to get this rite and the tutor I get hopefully would include this all in my hopes, what should I be studying in order to attain a GED. Please help.

English or maths? 😂😂

[@wesley6594]

oof i hope you follow up with 1:1 functions soon they're kinda important for domain and range

[@chrissinclair1745]

Can someone please explain to me how restricting the domain of x to (x >= 0) makes the green line go away? If I take x=4 (which is > 0, so satisfies the restriction), then root 4 is still both +2 and -2. Restricting the domain doesn't change that. Surely we should restrict the image set to >= 0, in other words ignore any negative outputs of inverse of f(x)?

[@rosepierce9382]

I think we're restricting both the domain and the range. The domain can't be negative because you can't get the square root of negative numbers across the real number system and the range can't be negative because the square root function only gives positive outputs.

Hi, i think the graph for 5:17 is inaccurate

[@nwgverified]

good revision for y10

why is the education so easy in australia

[@derrickmah3565]

It's really not, this is probably just regular maths - not HSC Extension maths or VCE Specialist Maths or even.... IB Higher Level Mathematics/Further Mathematics(Borderline 1st year/2nd year Uni Maths at Harvard/Oxford Level)(I know IB is international, but most private schools have it in Melbourne)

[@chrissinclair1745]

It's because they have Eddie Woo.

Jesus, can these students be any less excited?
