It is a first-order method in time, explicit in time, and is conditionally stable when applied to the heat equation. When used as a method for advection equations, or more generally hyperbolic partial differential equations, it is unstable unless artificial viscosity is included.

I think you have already proved this (pretty much). FTBS is only stable (and bounded) for 0<=c<=1. FTBS can be re-written: ϕ j ( n + 1) = ( 1 − c) ϕ j ( n) + c ϕ j − 1 ( n) So ϕ j ( n + 1) cannot lie outside ϕ j ( n) and ϕ j − 1 ( n). (It is a linear combination of ϕ j ( n) and ϕ j − 1 ( n) ).
