Given that the points (3, m-1) and (m, 2) are all on the image of a positive scale function, find the value of M 2, and find the analytic expression of the positive scale function

Given that the points (3, m-1) and (m, 2) are all on the image of a positive scale function, find the value of M 2, and find the analytic expression of the positive scale function

Let the function be y = KX
∵ points (3, m-1), (m, 2) are all on the image of positive scale function
∴m-1=3k
2=mk
The solution is K1 = 2 / 3, K2 = - 1
∴m1=3,m2=-2
The analytic expression of this positive proportion function is y = 2 / 3x or y = - 2x
