Question

Dada a função afim f(x) = - 2x + 3, determine: a) f(1) b) f(0) c) f(1/3) d) f(1/2)

Answer 1

Olá.

• f(x) = -2x + 3

1) f(1)

$f(1) = -2(1) + 3$
$f(1) = -2 + 3$
$f(1) = 1$

2) f(0)

$f(0) = -2(0) + 3$
$f(0) = 3$

3) f(1/3)

$f(1/3) = -2(1/3) + 3$
$f(1/3) = -2/3 + 3$
$f(1/3) = -2/3 + 9/3$
$f(1/3) = 7/3$

d) f(1/2)

$f(1/2) = -2(1/2) + 3$
$f(1/2) = -1 +3$
$f(1/2) = 2$

Bons estudos.
