Question

Dadas as funções f(x)=2x -6x-4 e g(x)=3x-5x+1 calcule f (3) f (-2) f(0)f (-0,2) g(1) g(-4) g(0) g(1/2)

Answer 1

F(3)= 2.3-6.3-4= 6-18-4= 6-22 = -16
F(-2)= 2.-2 -6.-2-4= -4+12-4 = 4
F(0)= 2.0-6.0-4=-4
F=(-0,2) = 2.-0,2-6.-0,2-4=-0,4+1,2-0,4= 0,4
g(1) =3.1-5.1+1= 3-5+1 = -1
g(-4)=3.-4-5.-4+1= -12 +20 +1 = 9
g(0)= 3.0-5.0+1= 1
g(1/2)= 3.1/2-5.1/2+1=3/2-5/2+1= -2/2+1= -2+2/2 = 0
