Answer:
The answer is A
Step-by-step explanation:
Because its not a function.
For x ∈ [ - b / ( 2a ) ; +oo ) , f is increasing; => x ∈ [ +2 ; +oo ).
Firstly, expand the equation.

Next, move the variable x to the left and all the constant to the right.

Then, solve for x.
Essentially, you must multiply 22 by 400. You get 8800 km apart for your answer.
