Let S be the set of all non-zero real numbers. Let S be a function such that f = {(x, y) e S Ã S: xy is positive))for all x, y in S such that x + y/ -0Let n be the number of possible values of f(4), and let S be the sum of all possible values of f(4). Find n times.

is this a multiple choice question?

if so it's a and c

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.

the end. : )
