Someone who's good at math as a ! for a healthy patient the normal hemoglobin level is 13.75 grams per deciliter +-1.75. which absolute value function describes this range, where x is the hemoglobin level per deciliter for a particular healthy patient, and y is the range of normal values? a) y=|x−13.75|, 0≤y≤1.75 b) y=|x+1.75|, 0≤y≤13.75 c) y=|x+13.75|, 0≤y≤1.75 d) y=|x−1.75|, 0≤y≤13.75
