Question

sendo f(x) = 2x - 2 e g(x) = -3x - 4, o valor de f(2) + g(-2) é?

Answer 1

Resposta:

f ( x ) = 2x - 2

f ( 2 ) = 2 . 2 - 2

f ( 2 ) = 4 - 2

f ( 2 ) = 2

g ( x ) = - 3x - 4

g ( -2 ) = - 3 . - 2 - 4

g ( -2 ) = 6 - 4

g ( -2 ) = 2

Answer 2

Resposta:

4

Explicação passo-a-passo:

f(x) = 2x - 2            

f(2) = 2.2 - 2

f(2) = 4 - 2

f(2)= 2

g(x) = -3x - 4

g(-2) = -3.(-2) - 4

g(-2) = +6 - 4

g(-2) = 2

Portanto, f(2) + g(-2) = 4
