Which of the following correctly describes the relationship between the graphs of

y=2^{x}

and

y=\log_{2}x

? (a) The two graphs are reflections of each other in the

y

–axis. (b) The graph of

y=\log_{2}x

can be obtained by shifting the graph of

y=2^{x}

one unit to the right. (c) The two graphs are reflections of each other in the line

y=x

. (d) The two graphs are reflections of each other in the

x

–axis.
