Transformation involves changing the form of a function.
The absolute value function is
The parent function of the absolute value function is:

When the function is translated 2 units to the right, the new function is:

From the function to be wider than the absolute function, the function must be stretched by a factor less than 1.
The possible function from the list of given options is
