Answer

Domain :$\qquad($0$,+\infty)$ Range :$\qquad(-\infty,+\infty)$ Vertical asymptote: $\qquad x=$0

Work Step by Step

We start with the graph of $f_{1}(x)=\log_{3}(x)$ (dashed blue). Since y$=2+\log_{3}(x)=f(x)+2$ its graph (red) is obtained by shifting $f_{1}(x)$ up by 2 units. Domain :$\qquad($0$,+\infty)$ Range :$\qquad(-\infty,+\infty)$ Vertical asymptote: $\qquad x=$0
