POR FAVOR VC PODE ME AJUDAR

Answer 1

Resposta:

$f(x) = \frac{ {x}^{2} + 1 }{x} \\ f(3) + f( \frac{1}{3} ) \\ \\ \frac{ {3}^{2} + 1}{3} + \frac{ {( \frac{1}{3}) }^{2} + 1}{ \frac{1}{3} } \\ \\ \frac{9 + 1}{3} + \frac{ \frac{1}{9} + 1 }{ \frac{1}{3} } \\ \\ \frac{10}{3} + \frac{ \frac{1 + 9}{9} }{ \frac{1}{3} } \\ \\ \frac{10}{3} + \frac{ \frac{10}{9} }{ \frac{1}{3} } \\ \\ \frac{10}{3} + \frac{10}{9} \times \frac{3}{1} \\ \\ \frac{10}{3} + \frac{10 \times 3}{9 \times 1} \\ \\ \frac{10}{3} + \frac{30 \div 3}{9 \div 3} \\ \\ \frac{10}{3} + \frac{10}{3} = \frac{10 + 10}{3} = \frac{20}{3}$
