Answer:

Step-by-step explanation:
The function is
, whose first derivative is:

Let equalize the derivative to zero:





The solutions are given by the following inverse trigonometric function:

The answer is 40 because if you do simple division you will get that 800/20 is 40
I got -2(2x-3) but it should be C.-4x-2
