Please see the graph.

Work Step by Step

The green line is the function $y=2^x$. The purple line is $y=log_2 x$. $y=2^x$ $x=0$ $y=2^x$ $y=2^0$ $y=1$ $x=1$ $y=2^x$ $y=2^1$ $y=2$ $x=2$ $y=2^x$ $y=2^2$ $y=4$ $(0,1)$, $(1,2)$, and $(2,4)$ are on the curve of the function $y=2^x$. $y=log_2 x$ $x=4$ $y=log_2 x$ $y=log_2 4$ $2^y=4$ $2^2=4$ $y=2$ $x=2$ $y=log_2 x$ $y=log_2 2$ $2^y=2$ $2^1=2$ $y=1$ $x=1$ $y=log_2 x$ $y=log_2 1$ $2^y=1$ $2^0=1$ $y=0$ $(1,0)$, $(2,1)$, and $(4,2)$ are on the curve of the function $y=log_2 x$.
