Refer to the graph below.
Work Step by Step
To graph the given function, perform the following steps:
(1) Graph the parent function $y=\log_2{x}$. (Refer to the green graph below.)
(2) Stretch the parent function's graph vertically by a factor of $2$. This can be done by doubling each value of $y$ without changing the value of $x$. (Refer to the blue graph below.)
