Maths help appreciated!
Hey, so I got exams soon, and I'm trying to revise and failing with this question
http://i.imgur.com/FmP1E.png - Quartic graphs & functions
I know how to do question a) and b), but I'm not sure about c).
If you could help me, that'd be greatly appreciated
Edit: Resolved, thanks for your comments everyone.

[quote=SilentXynh]Draw the function, find the range of said function.
That should be the domain of your inverse function, but make sure to check which part of it is actually valid.[/quote]
given http://www.wolframalpha.com/input/?i=y%3D-x^4-2x^3%2B3x^2%2B4x-4
this means ran(f) = [0,-inf)
right?

[quote=Ricci]after you graph the equation u find in part A, find the domain of it? (all the x-values it hits). then switch y=xblah blah blah for x=yblah blah blah and solve for y, to find the inverse[/quote]
Isn't the domain = all real numbers?
I ask because Basil has helped me in the past.
Well my friend asked me, and yeah I've asked others.
