In the region 0-2, the first derivative has a zero at x=1, and the second derivative (slope of the first derivative line) is positive. This means f(x) will have a minimum at x=1.
Likewise, in the region 4-6, the second derivative is negative and the first derivative is zero at x=5, indicating a maximum there.
These observations narrow the selection to choices A or C. The derivative curve is continuous at x=2 and x=4, so there will not be any discontinuities in f(x)--eliminating selection C.
The best choice is A.

Answer: x = -1 and y = 3
Step-by-step explanation:
Let's start by solving for
Add 5y to both sides
Now we need to divide both sides by 10
That's not the answer for x. We are not done yet :)
Now we need to substitute for
Now we need to simply both sides
Now we need to add 25 to both sides
We have the valuee for y! Now we need to find the value for x
To find the value of x, we need to substitute 3 for y in:
Therefore,
The answer is x = -1 and y = 3
