Answer:
Option A is correct
Step-by-step explanation:
Domain is the set of all input values ( i,e x-values) where function is defined.
In the given figure:
Input values are:
From top to bottom:

Now, sort them to get:
-5, -3, 1, 2, 6
by definition of domain:
Therefore, the domain of the function is:

That's a 33% increase.
I calculated this using the formula:
Where n = the new value (16 in your question), o = the old value (12 in your question) and the result is outputted as a percent increase. You can check that this is correct by finding 33% of 12, adding the result to 12, and checking that the result equals your "new" number.
Note that 33% is only an approximation as your question requires a number rounded to the nearest whole.
