Question 740570
Try to sketch this description:


Start with the graph {{{log(3,x)}}}, which has an asymptote x=0 toward the left and not defined for {{{x<0}}}, and is an increasing function, and crosses the x axis at x=1.


If you REFLECT {{{log(3,x)}}} around the horizontal x axis, you have {{{-log(3,x)}}}.  


If you raise the graph by two units (move upward by two units), then you have {{{2-log(3,x)}}}.


{{{graph(300,300,-2,12,-2,12,2-log(3,x))}}}
