$${f}\left({x}\right)\:=\:{x}^{\mathrm{2}} −{x}−\mathrm{2} \\ $$$${f}\left(−\mathrm{2}\right)\:=\:\mathrm{4} \\ $$$$\mathrm{2}{f}\left(−\mathrm{2}\right)\:=\:\mathrm{8} \\ $$$${f}\left(\mathrm{2}{f}\left(−\mathrm{2}\right)\right)\:=\:{f}\left(\mathrm{8}\right)\:=\:\mathrm{64}−\mathrm{8}−\mathrm{2}\:=\:\mathrm{54} \\ $$
