Question

dada a funçao definida por f(x)=$\frac{3x-1}{2x+1}$ ,calcule f(2)

Answer 1

.$f(x)= \frac{3x-1}{2x+1} \\ \\ f(2)= \frac{3(2)-1}{2(2)+1} \\ \\ f(2)= \frac{6-1}{4+1} \\ \\ f(2)= \frac{5}{5} \\ \\ f(2)=1$

Answer 2

Olá, resolução!

$f(x)= \frac{3x-1}{2x+1} \\ \\ \boxed{f(2)= \frac{3*2-1}{2*2+1} = \frac{6-1}{4+1} = \frac{5}{5} =\boxed{1}}$

Espero ter ajudado, valeu! ^^
