It is known that the function y = [M + 2] x to the power of M + 4 - 4x + 1 [x ≠ 0] is a linear function Multiplication of powers of the same base

It is known that the function y = [M + 2] x to the power of M + 4 - 4x + 1 [x ≠ 0] is a linear function Multiplication of powers of the same base

The M + 4 power of function y = [M + 2] x - 4x + 1 [x ≠ 0] is a linear function
There are two cases
1. M + 4 = 1, M = - 3, so the M + 4 power of y = [M + 2] x - 4x + 1 = - x-4x + 1 = - 5x + 1
2. M + 4 = 0 leads to M = - 4, so the M + 4 power of y = [M + 2] x - 4x + 1 = - 2-4x + 1 = - 4x-1
