Answer
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 $y=log_2 x$.
