Hello Everybody ,
I am working on some exercises here , about the domains of some given functions , but my solutions differ than the book ones... Am i wrong in something or the book has indeed mistakes ???
Asks for the domain of the function : f(x) = logx4
The solution it gives me is : D(f) = (0,1)u(1,-oo).
Firstly , why (1,-oo)? i think it's obviously a mistake , what's your opinion?
Also , do i really need (0,1) wouldn't it be better if i only had D(f) = (1,+oo) ?
Thaks in advance for your answers !!!
