Answer:
The inverse f-1(x) = (2 - x)/4 + 1.
Step-by-step explanation:
Let y = -4 /(x - 1) + 2
-4/(x - 1) = y - 2
x - 1 = (y - 2) / -4
x = -(y - 2)/4 + 1
x = (2 - y)/ 4 + 1
Now replace x by f-1(x) ( the inverse) and y by x:
f-1(x) = (2 - x)/4 + 1.
4(x^2 - 1)(x - 3)(x + 3)^2 = 0
(x + 1)(x - 1)(x - 3)(x + 3) = 0
x = -1, 1, 3, -3
