For the inverse variation function y = k/x (where x, k > 0), what happens to the value of y as the value of x increases?

Since k is a positive constant, y = k/x gets smaller as the positive value of x gets larger. For example, increasing x from 2 to 4 changes y from k/2 to k/4, which is smaller. Therefore, y decreases; the correct choice is “decreases.”
