Given the intersection point P (- 3,4) of the image of a positive scale function and an inverse scale function, find the relationship between the two functions and copy the table
Let the analytic formula of positive proportion function be y = KX, and that of inverse proportion function be y = m / X. K and m are constants not equal to 0
Substituting x = - 3, y = 4 into y = KX, we get the following result:
-3k=4,k=-4/3
The analytic expression of positive proportion function is y = (- 4 / 3) X
Substituting x = - 3, y = 4 into y = m / x, we get the following result:
m/(-3)=4
m=-12
The analytic expression of inverse sequence function is y = - 12 / X
