For the function y = (M-4) x + (m2-16), when m= It is a positive proportional function when M It is a function of degree

According to the definition of a function, if the relationship between two variables X and y can be expressed in the form of y = KX + B (k, B are constants, K ≠ 0), then y is a function of X, where x is an independent variable and Y is a dependent variable. When B = 0, then y = KX (K ≠ 0) and Y is a positive proportional function of X, then m2-16 = 0 is obtained. The solution is m = ± 4, ∵ M-4 ≠ 0, ∵ m ≠ 4, so it is a positive proportional function when m = - 4 When M-4 ≠ 0, i.e. m ≠ 4, it is a linear function
