Answer:

And on this case we can use the product rule for a derivate given by:

Where
and
And replacing we have this:

Step-by-step explanation:
We assume that the function of interest is:

And on this case we can use the product rule for a derivate given by:

Where
and
And replacing we have this:

The best way to solve this problem is by plugging in each answer choice for both equations and seeing which one works. You can already see that choice A doesn't work because -1 is not greater than or equal to 4. That means you just need to test choices B and C!
Choice B (4, -2)

2 is not greater than or equal to 6, so choice B doesn't work.
Choice C (4, 2)

Since 6 is equal to 6 and 4 is equal to 4, choice C works!

Answer: C) (4, 2)
