Step-by-step explanation:
The correct answer is B) The set of all first elements of the function. Let's say you had these three points on a graph of a function: (0.9), (2.6), (4,7). The domain of these three points would be (0,2,4). The domain is just the input for which the function is defined. Hope this helps.
For this case we propose a rule of three:
31700 ------------> 8.8%
x ----------------------> 100%
Where "x" represents the number of copies sold to date.

Thus, to date 360,227 copies of the book have been sold.

Divide the number of fast balls by the total number of pitches:
240 / 384 = 0.625
