    ok so i multiply that funtion by itself to the -1 power?

    the -1 notation here denotes the inverse of the function .. not really a power

    given a function \[y=\frac{32}{x+3}\] the inverse swapps x and y, so the inverse of this is \[x=\frac{32}{y+3}\]

    lets work the inverse a little more .. just so things loook normal \[x=\frac{32}{y+3}\] \[y+3=\frac{32}{x}\] \[y=\frac{32}{x}-3=g^{-1}(x)\]

    so, \[g^{-1}*g=(\frac{32}x-3)(\frac{32}{x+3})\] plug in x=5 and find the product

    ahhh, that changes things, the open "o" means a composite, not a multiplication of the 2 of them

    yes, if the input is 5, the output is 5 ... its a special property of composing inverses of each other

    only if the functions are inverses of each other does that work. If they are not inverses the input and output can be different
