It is known that the function y = (2m-8) x is m2-4m + 3 power. 1. When m takes any value, it is a positive proportional function. 2. When m takes any value, it is a positive proportional function It's an inverse scale function

y=(2m-8)x^(m²-4m+3)
It's a positive scale function
So M & # 178; - 4m + 3 = 1
(m-2)²=2
M = 2 ± 2 under root sign
It's an inverse scale function
So M & # 178; - 4m + 3 = - 1
(m-2)²=0
m=2
