(sorry guys, latex is being uncooperative. towards the end that says: and f(1)=4, find f(9).) Could anyone suggest where i might begin this problem?

Or, work backwards: f(9)= 2(9)+ f(8)= 18+ (2(8)+ f(7))= 18+ 16+ (2(7)+ f(6)), etc. (It's generally not a good idea to put text into LaTex. If you didn't mean to then you probably missed the [/ math] at the end.)
