1. It is known that y is the inverse proportional function of X, and when x = 2, y = 8. Find the functional relationship between Y and X? 2, and find the value of y when x = 1 / 2 When x takes what value, y = 4 / 3?

1. Let y = K / X. since y = 8 when x = 2, k = 16, that is, y = 16 / X
2, substituting x = 1 / 2 into y = 16 / x, y = 32
