A

Step-by-step explanation:

Consider the parent function The graph of this function is represented as red graph in attached diagram.

Now consider the function

Remind main translations of the graph of the function

In your case, the graph of the function is translated graph of the function 2 units to the left (blue graph). So, correct answer is option A.

the answer is b.)
