Question

considere a seguinte função: f(x)
$\frac{2x - 6}{4}$ calcule:
A) f(-3)
B) f(0)
C) f(2)
D) f(5)

Answer 1

Resposta:

Boa Sore!

Explicação passo-a-passo:

$f(x)=\frac{2x-6}{4}=>\frac{2(x-3)}{4}=>\frac{x-3}{2}\\\\f(-3)=\frac{-3-3}{2}=\frac{-6}{2}=-3\\\\f(0)=\frac{0-3}{2}=-\frac{3}{2}\\\\f(2)=\frac{2-3}{2}=-\frac{1}{2}\\\\f(5)=\frac{5-3}{2}=\frac{2}{2}=1$
