Question

dada a funçao afim f(x)=3x-2,calcule f(2)-f(1)

Answer 1

Olá!!!

Resolução!!!

f ( x ) = 3x - 2

f ( 2 ) = 3 • ( 2 ) - 2
f ( 2 ) = 6 - 2
f ( 2 ) = 4

f ( 1 ) = 3x - 2
f ( 1 ) = 3 • ( 1 ) - 2
f ( 1 ) = 3 - 2
f ( 1 ) = 1

= f ( 2 ) - f ( 1 )
= 4 - 1
= 3

Espero ter ajudado!!!!

Answer 2

Boa Noite!


•F(x)=3x-2            •Calcule F(2)-F(1)

F(2)=3*(2)-2 => 6-2=> 4
F(1)=3*(1)-2=>3-2=> 1

F(2)-F(1)=> 4-1 => 3
