The answer to the sunset question is 16 F.
Work Example:
With the number -2, you can order the work simple like these examples over here.
18 + (-2) = 16.
The problem is usually written like this, and here is a little trick. When a positive number is added to a negative number, instead of adding itself, it subtracts the positive form of the negative number with 18, which is our positive number.
18 - 2 = 16.
If you place the -2 as the second number in the equation, the negative works nicely and looks like a minus sign. Or, you can do it in a different way.
You're using Rolle's theorem. This theorem states that, if a function is continous in ![[a,b]](https://tex.z-dn.net/?f=%20%5Ba%2Cb%5D%20)
and differentiable in 
, and 
, then there exists a middle point ![c \in [a,b]](https://tex.z-dn.net/?f=%20c%20%5Cin%20%5Ba%2Cb%5D)
such that 
In other words, if a continous and differentiable function starts and ends at the same height, then it has a maximum or minimum.
In your case, since the function is differentiable in the closed interval, it is also continuous in the closed interval (differentiability implies continuity), and also being differentiable in the closed interval obviously implies that the function is differentiable in the open interval. Also, you're given that the function evaluates to 4 at both extreme points, so the hypothesis of the theorem are granted.
