Answer:
the answer is C
hope this helps
have a good day :)
Step-by-step explanation:
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
7 divided by 1 is 7 so you would do long division
Answer:
x^2 + 6
Step-by-step explanation:
X squared or "x^2" just means X times X. For example, 9^2=81 which is the same as 9x9. Then just add 6.
