Functions f and g are defined by

f : x/rightarrow k - x

g : x/rightarrow 9/x+2,
k is a constant and X /neq
– 2

(i) Find the values of k for which the equation f(x) = g(x)
has two equal roots and solve the equation f(x) = g(x)
in these cases

(ii) Solve the equation fg (x) = 5
where k = 6

(iii) Express g
-1 (x)
in terms of x
