If the image of the inverse scale function passes through a point (- 2,4), the analytic expression is

Let the analytic expression of inverse sequence function be y = K / x, and substitute x = - 2, y = 4 into y = K / X to get the following result:
k/(-2)=4
k=-8
The analytic expression of inverse sequence function is y = - 8 / X
