Vertical asymptote:$\quad x=0$ The domain of g:$\quad (0,+\infty)$ The range of g:$\quad (-\infty,+\infty)$ .
(See table 4.5, Transformations involving Logarithmic Functions) $f(x)=\log_{2}x$ $g(x)=$2$+\log_{2}x=f(x)+$2 so the graph of $g(x)$ (blue) is obtained from the graph of f(x) (red) by 1. reflecting it about the x axis (blue, dashed) and 2. vertically stretching it by factor 2.
