Question

Considera a função g definida por: g(X)=3x+2
G(-1), g(0),g(4)

Answer 1

Olá!

$g(x) = 3x + 2$

- g(-1) :

$g( - 1) = 3 \times ( - 1) + 2 \\ g( - 1) = - 3 + 2 \\ g( - 1) = - 1$

- g(0) :

$g(0) = 3 \times (0) + 2 \\ g(0) = 0 + 2 \\ g(0) = 2$

- g(4) :

$g(4 )= 3 \times (4) + 2 \\ g(4) = 12 + 2 \\ g(4) = 14$

Answer 2

g(x) = 3x + 2

substituindo :

g(-1) = 3.(-1) + 2
g(-1) = -3 + 2 = -1

g(0) = 3.0 + 2
g(0) = 0 + 2 = 2

g(4) = 3.4 + 2 
g(4) = 12 + 2 = 14

Espero ter ajudado!
