It is the graph of log base 2, with a horizontal translation of 1 unit right.

#### Explanation:

To graph how to graph

From that graph, the value of k is -1, which means that the graph of log base 2 is translated 1 unit right.

Also note that due to this translation, the vertical asymptote is translated 1 unit left, and would then become x=1.
