You can put this solution on YOUR website!
F o g= ln (1/x)= -ln x
\n" ); document.write( "One can't have an ln of a negative number or 0, so x must be positive. That is the domain., (0,oo)
\n" ); document.write( "The range is (-oo, oo). When x is less than 1, -ln (x) becomes positive. When x=1, ln(x)=0. When x >1, -ln (x) becomes negative. \r
