the function f is such that f(x) = (3x + 2)3 ? 5 for x ? 0.
ii) Obtain an expression for f?1(x) and state the domain of f?1.

ohk..
here
y=
to get inverse you make x the subject
-------------
-------------
now range of f(x)= domain of f
-1
(x)
range of f(x) can be as the domain for it is given as x>=0
sub 0 in f(x) y>=3
this is the domain of the inverse function
D of f
-1
(x) x>=3
