What is the smallest integer that is not in the domain of f(x)=sqrt( pi - x) ?
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
So like Alan said, what is the smallest possible integer that fits this restriction?
