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

do you know how to find an inverse?

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

so now i divide?

amistre64

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

amistre64

so, \[g^{1}*g=(\frac{32}x3)(\frac{32}{x+3})\]
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

so if there is an o don't multiply make input sam as output?

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