B. f^-1(x)=3x+2/x-5;domain of f;{x/x not equal -5};range of f:{y/y not equal 5}
C .f^-1(x)=x+5/3x-2;domain of f:{x/x not equal -5}; range of f {y/y not equal 2/3}
D. f^-1(x)=5x+2/3+x;domain of f:{x/x not equal -5}; range of f: y/y not equal -3}
Please Help..I am tearing my hair out with these.....

Your representations of the problems are very difficult to decipher. I think for the first one you mean:
,
In which case,
Use the following rules:
The log of the product is the sum of the logs:
The log of the quotient is the difference of the logs:
→ → → → →
Answer A.
Write back and we'll talk about the rest of them.
