anthropos Posted June 5, 2007 Share Posted June 5, 2007 g(x) = ln (x-2), x>2 (x is a real number) The question says find g inverse. I have no problem finding the function, but I met difficulty in looking for the domain. The domain of g inverse is the range of g, but I cannot find the range of g, so do we have to state the domain of g inverse? Link to comment Share on other sites More sharing options...
Ducky Havok Posted June 5, 2007 Share Posted June 5, 2007 The range of a natural log is all real numbers, (as x-2 approaches 0, ln(x-2) approaches negative infinity, as x-2 approaches infinity, ln(x-2) approaches infinity) so you should be able to get your domain from that.

the tree Posted June 5, 2007 Share Posted June 5, 2007 I cannot find the range of g(x)You've already told us the range, and the domain of g(x)[math']g(x) = \ln(x-2) \quad x>2 \quad x \in \mathbb{R}[/math] Link to comment Share on other sites More sharing options...
