Respuesta :
F(x) = 3x
F(7) = 21
g(x) = -x + 1
g(7) = -7 + 1 = -6
(F x g)(7) = (21) (-6) = -126
F(7) = 21
g(x) = -x + 1
g(7) = -7 + 1 = -6
(F x g)(7) = (21) (-6) = -126
(f o g)(x) = 3(- x + 1)
= - 3x + 3
Plug in 7 to this equation
- 3(7) + 3
- 21 + 3
- 18
(f o g)(7) = - 18
= - 3x + 3
Plug in 7 to this equation
- 3(7) + 3
- 21 + 3
- 18
(f o g)(7) = - 18
