Funksíyanyñ bahalaryny tapyn̆. Berilgen nokatlarda, 1. \( y = -1 \): \( x = -1 \) üçin \( y = -1 + \frac{1}{-1} = -2 \) 2. \( y = \frac{1}{2} \): \( x = 0.5 \) üçin \( y = 0.5 + \frac{1}{0.5} = 2 \) 3. \( y = 1 \): \( x = 1 \) üçin \( y = 1 + \frac{1}{1} = 2 \) 4. \( y = 2 \): \( x = 1 \) ýa-da \( x = 2 \) üçin \( y = 2 + \frac{1}{2} = 2.5 \). Netijede, berilen nokatlarda funksiýaň bahalaryny tapyp bilersiň. Bu funksiýa, sanlaryň arasynda kesgitlemesi bilen saýlaw etmegiň gowy usulydyr.
