Question

Решите пожалуйста номер 258

Answer 1

$y = x + frac{1}{x} \ g(4) = 4 + frac{1}{4} = 4 + 0.25 = 4.25 \ \ g( frac{1}{3} ) = frac{1}{3} + frac{1}{ frac{1}{3} } = frac{1}{3} + 3 = 3 frac{1}{3} \ \ g( - 5) = - 5 + frac{1}{ - 5} = - 5 - frac{1}{5} = - 5 frac{1}{5} = - 5.2 \ \ g( - frac{1}{7} ) = - frac{1}{7} + frac{1}{ - frac{1}{7} } = - frac{1}{7} - 7 = - 7 frac{1}{7}$
