Answer:
f^-1 (x) = 2X + 8
Step-by-step explanation:
Let's make f(x) = y
Y = X/2 - 4
So to find the inverse, switch the y with the x like so:
X = Y/2 - 4 (isolate the Y value)
X + 4 = Y/2 (multiply both sides by 2)
2(X + 4) = Y
Y = 2X + 8
So f^-1 (x) = 2X + 8
The additive inverse of something is the number that, if you add it to the original number, you get 0.
The additive inverse of 5, for example, is -5. 5 plus -5 = 0.
You should be able to see how additive inverses are always going to be just the original number with the signs changed. (i.e., times -1)
The additive inverse of -4a would be 4a. -4a + 4a = 0.
