Respuesta :
f(x) = \sqrt(x)
g(x) = 2\sqrt(x)
(f-g)(x) = \sqrt(x) - 2\sqrt(x)
(f-g)(144) = \sqrt(144) - 2\sqrt(144)
(f-g)(144) = 12 - 24
(f-g)(144) = -12
g(x) = 2\sqrt(x)
(f-g)(x) = \sqrt(x) - 2\sqrt(x)
(f-g)(144) = \sqrt(144) - 2\sqrt(144)
(f-g)(144) = 12 - 24
(f-g)(144) = -12
f(144)= sqrt(144)+12 g(144)= 2(sqrt(144))
f(144)= 12+12 g(144)= 2(12)
f(144)=24 g(144)=24
(24)-(24)=0
f(144)= 12+12 g(144)= 2(12)
f(144)=24 g(144)=24
(24)-(24)=0
