Question

Dada a função g(x)=2x-6x-4,calcule,g(3) e g(-2)???

Answer 1

g(x) = 2x - 6x - 4

g(3) = 2.3 -6.3 - 4
g(3) = 6 - 18 - 4 = -16

g(-2) = 2.(-2) - 6(-2) - 4
g(-2) = -4 + 12 - 4 = 4

Espero ter ajudado.

Answer 2

g(x)=2x-6x-4
g(3)=2.3-6.3-4
g(3)=6-18-4
g(3)=6-22
g(3)=-16
g(-2)=2.(-2)-6.(-2)-4
g(-2)=-4+12-4
g(-2)=8-4
g(-2)=4
