Answer:
The graph in the middle is the one representing

Explanation:
Notice that the graph of
is an exponential form that approaches zero when x approaches negative infinity, and grows to large positive values as x becomes larger. In fact, the very first graph is the oe representing such.
The graph of
on the other hand, should be a vertical translation of the previously mentioned exponential graph, that moves the entire graph down exactly two units. SO it is the middle graph the one that shows this behavior.
