My attempts, I've drawn the function, split it into two parts and found out that it's the area between curve $\ln (x-2)$ , x axis and y axis. How do I integrate, using what limits? Thanks!! The answer is $4 \ln ( 2 + \surd 3) - 2 \surd 3$.

$y = \ln(x^2+4)$ increases w/o bound in quad I ... you sure the problem statement is correct?
