Evaluate the function for the indicated input and interpret the result.The table lists the number of persons voting in an election by election year and sex, for a small community. 
Let this table be a partial numerical representation of a function f, where 
computes the number of persons who voted in the year x whose sex is y. Evaluate 
Interpret the result.
A. f (1992, Male) - f (1992, Female) = 120
In the year 1992, 120 more men voted than women.
B. f (1992, Male) - f (1992, Female) = 111
In the year 1992, 111 more men voted than women.
C. f (1992, Male) - f (1992, Female) = -120
In the year 1992, 158 more women voted than had previously voted in 1988.
D. f (1992, Male) - f (1992, Female) = 158
In the year 1992, 158 more men voted than women.
