Question

dada a função afim f(x) = - 2x + 3, determine: f(2/3)

Answer 1

Resposta:

f(2/3) = 5/3.

Explicação passo a passo:

f(x) = -2x + 3.

f(2/3) = -2x2/3 + 3

= -4/3+3

= -4/3 + 3/1 = -4/3 + 9/3 = 5/3.

f(2/3) = 5/3.

Answer 2

Resposta:

$\textsf{Leia abaixo}$

Explicação passo a passo:

$\mathsf{f(x) = -2x + 3}$

$\mathsf{f(2/3) = -2\:.\dfrac{2}{3} + 3}$

$\mathsf{f(2/3) = -\dfrac{4}{3} + 3}$

$\mathsf{f(2/3) = \dfrac{-4 + 9}{3}}$

$\boxed{\boxed{\mathsf{f(2/3) = \dfrac{5}{3}}}}$
