a closed box with a square base is made of material that's costs 10$ per m squared for the top and bottom and 5$ per meter squared for the sides.

express the cost of the box as a function of x and h. ( h being the height and x being the length and width)

if the voloume is 8 meters cubed than express the cost as a function of x alone.

also if you can help h(x) = x cubed/ 2

how do I find that inverse ?

How do I find a rule

and how do you show that they are inverses ?

also are all inverses reflections of some sort??

Please help me , I work so hard but I'm really confused!!

:confused:

Thank you so much!
