You can't take the square root of a negative value (not while dealing with real numbers, anyway), so what is the first integer bigger than pi?

 

Here's a picture to help:

f(x)=sqrt( pi - x)

Smallest integer that is NOT in the domain.

Well all negative values of x will be in the domain because there will be a sqrt value for all of those.

the ones that won't be in the domain are those where

$$\\\pi-x<0\\
\pi x>pi$$

 

So like Alan said, what is the smallest possible integer that fits this restriction?
