Explanation Given information: f ( x ) = x + 1 x , x > 0 . Fact used: If f ' changes from negative to positive at p, then f has a local minimum at p. If f ' changes from positive to negative at p, then f has a local maximum at p. Calculation: f ( x ) = x + 1 x , x > 0 (Given) Differentiating with respect to ‘x’, we get f ' ( x ) = 1 − 1 x 2 Equating f ' ( x ) = 0 ⇒ 1 − 1 x 2
