Question

f: ir - definida por f(x) = 2x - 1/3, calcule: f(0)= , f(-2)= , f (1/3) =

Answer 1

$\boxed{\boxed{f(x) = 2x - \frac{1}{3}}}$

$f(0) = 2(0) - \frac{1}{3} = \boxed{\frac{-1}{3}}$

$f(-2) = 2(-2) - \frac{1}{3} = -4 - \frac{1}{3} = \frac{-12-1}{3} = \boxed{ \frac{-13}{3} }$

$f( \frac{1}{3}) = 2( \frac{1}{3}) - \frac{1}{3} = \frac{2}{3} - \frac{1}{3} = \boxed{ \frac{1}{3}}$

Espero ter ajudado. :))
