You can put this solution on YOUR website!
If you need help with composite functions, then email me. You need to include the actual functions f(x)= and g(x)=
Basically, there is no way to solve f(-1) when you don't have a function to plug it in for. That is why you are always given a statement like, "If f(x)=4x+3 then find f(4)". We wouldn't know what to do if we were not given the "If" portion.
