It is known that y is the inverse proportional function of X, when x = 2, y = 6 1. Write the functional relationship between Y and x 2. Find the value of y when x = 4

∵ y is the inverse proportional function of X
∴y=K／x
Substituting x = 2, y = 6 into y = K / x, we get the following result:
6=K／2
K=12
The functional relationship between Y and X is y = 12 / X
When x = 4, y = 12 / 4 = 3
