Step-by-step explanation:
Answer: It would be x^2 I think

Thats what you would use, so now 2/10 is .2 When you divide so you move the decimal so 20%
The percent increase is 20%
Let d(x) = 2x - 4
Or
y = 2x - 4
We have replace x = y
x = 2y - 4
Now Isolate "y"
x + 4 = 2y
Pass "2" dividing
(x + 4) / 2 = y
y = x/2 + 2
Or
d(x)^-1 = x/2 + 2
