Answer:
A
Step-by-step explanation:
It is usually sufficient to look at one section of the graph to answer a question like this. Often the best choice is the section that has a solid dot at the end of the curve. Here, that is the right section.
The left end of the right section is at x=-2, so that part of the function is defined for x ≥ -2. The line to the right has a positive slope, so the coefficient of x will be positive.
Only one answer choice has a positive x-coefficient for x ≥ -2.
We're looking for a scalar function such that
. That is,
Integrate the first equation with respect to :
Differentiate with respect to :
Integrate with respect to :
So is indeed conservative with the scalar potential function
where is an arbitrary constant.
