Question

Seja a função f(x) =3x -4 , calcule:

f( 1)

f( 2 )

f(0,5 )

f(-0,5)

f(15)

f(-2,5)

f(0,1)

f(0)

Answer 1

Explicação passo-a-passo:

f(x) = 3x -4

f(1) = 3.1-4

f(1) = 3-4

f(1) = -1.

f(x) = 3x-4

f(2) = 3.2-4

f(2) = 6-4

f(2) = 2

f(x) = 3×-4

f(0,5) = 3. 0,5 -4

f(0,5) = 1,5 - 4

f(0,5) = -2,5

f(x) =3×-4

f(15) =3.15-4

f(15) = 45-4

f(15) = 41

f(x) =3x-4

f(-2,5) =3.(-2,5)-4

f(-2,5) = -7,5-4

f(-2,5) = -11,5

f(x) =3×-4

f(0,1)=3.0,1-4

f(0,1)=0,3-4

f(0,1)= -3,7

f(x) =3x-4

f(0) =3.0-4

f(0) =0-4

f(0) = -4.

Answer 2

Resposta:

F(1)=3×1-4=_1

f(2)=3×2_4=2

f(0.5)=3×0,5_4=2,5

f(15)=3×15_4=41

f(_2,5)=3×2,5-4=3,5

f(0,1)=3×0,1-4=_3,7

f(0)=3×0_4=_4
