Third option
![y = |x + 1|](/tpl/images/0498/0336/a8048.png)
Step-by-step explanation:
The main function
![f (x) = | x |](/tpl/images/0498/0336/40e79.png)
has its vertex in the point (0, 0)
The function shown in the graph has its vertex in the point (-1, 0)
The transformation made to f (x) that moves its vertex one unit to the left is:
![y = f (x + 1)](/tpl/images/0498/0336/36e46.png)
After this transformation the new function is:
Note that this function corresponds to the function plotted in the image.
Therefore the answer is the third option
