The composite function fg(x) means that...
g acts on x first, then f acts on the result.
f acts on x first, then g acts on the result.
To calculate the inverse function f(x)^-1, you...
times f(x) by -1.
divide f(x) by 1/x.
change the subject of the formula.
replacing x's with y's.
The graph of f(x)^-1 is ...
