Question

F (x)= X+1/x
Calcule:

F (1/2)

Answer 1

Olá,tudo bem com você??


$f(x) = \frac{x + 1}{x} \\ \\ f( \frac{1}{2} ) = \frac{ \frac{1}{2} + 1 }{ \frac{1}{2} } \\ \\ f( \frac{1}{2} ) = \frac{ \frac{2 + 1}{2} }{ \frac{1}{2} } \\ \\ f( \frac{1}{2} ) = \frac{3}{2} \div \frac{1}{2} \\ \\ f( \frac{1}{2} ) = \frac{3}{2} \times \frac{2}{1} \\ \\f( \frac{1}{2} ) = \frac{3.2}{2.1} \\ \\ f( \frac{1}{2} ) = \frac{6}{2} \\ \\ f( \frac{1}{2} ) = 3$

espero ter ajudado!

boa noite!

Answer 2

Olá,

$f(\frac{1}{2})=\frac{\frac{1}{2}+1 }{\frac{1}{2}}\\\\f(\frac{1}{2})=\frac{\frac{3}{2}}{\frac{1}{2}}\\\\ f(\frac{1}{2})=\frac{3.2}{2.1}\\\\ f(\frac{1}{2})=\frac{6}{2}\\\\ f(\frac{1}{2})=3$
