1. The problem statement, all variables and given/known data Q1 [|x+2|]=2[|x|]-3 Q2 If f is even and g is odd, is fog even, odd or neither 2. Relevant equations 3. The attempt at a solution Q1 Not sure. Can someone please give me a start on this? I think if I knew some properties of greatest integer functions I could work it out Q2 Let f(-x)=f(x) and g(-x)=-g(x) All I need to know is what fog(-x) equals. The rest I can do myself. Thanks a lot.
