It is known that the image of y = ax and y = (4-A) / X has two intersections, and the abscissa of one intersection is 1, then the analytic expression of inverse scale function is obtained__

It is known that the image of y = ax and y = (4-A) / X has two intersections, and the abscissa of one intersection is 1, then the analytic expression of inverse scale function is obtained__

From the meaning of the question, when x = 1, the Y values of the two functions are equal, that is, a = 4 - A
So a = 2
Then the analytic expression of inverse scale function is y = 2 / X
Hope to help you.
