(i) Solve the inequality, leaving your answers in exact form,
(ii) Hence solve
The functions f and g are defined as follows:
Where λ is a constant.
(i) Given that gf exists, find the largest value of λ.
In the rest of the questions, use the value of λ found in part (i).
(ii) On the same diagram, sketch the graph of , and , showing clearly the relationship between the graphs.
(iii) Hence find the exact solution of
