Induction and Relations and Functions, math homework help

I have a worksheet on Induction and Relations and functions that I could use some help with.  I need to have explanations for the answers/ work shown, please.  I want to compare to what I think is correct.  For question #16 & #17 I have included the pages it refers to.

Thanks

Patrick
