The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: WebIn particular, if f ′ (x) = 0 f ′ (x) = 0 for all x x in some interval I, I, then f (x) f (x) is constant over that interval. This result may seem intuitively obvious, but it has important implications that are not obvious, and we discuss them shortly. Theorem 4.6. Corollary 1: Functions with a Derivative of Zero.
