(goh)(4) = g (h (4))
H (4) = 4^3 + 4×3 = 76
g (h (4 ))= g (76) = 76 sqrt 6
H (4) = 4^3 + 4×3 = 76
g (h (4 ))= g (76) = 76 sqrt 6

g(x) = √(6 x)
h(x) = x³ + 3x
(g ∘ h)(x)
= g(h(x))
= g(x³ + 3x)
= √[6(x³ + 3x)]
= √(6x³ + 18x)
(g ∘ h)(4)
= √(6 * 4³ + 18 * 4)
= 2√114
h(x) = x³ + 3x
(g ∘ h)(x)
= g(h(x))
= g(x³ + 3x)
= √[6(x³ + 3x)]
= √(6x³ + 18x)
(g ∘ h)(4)
= √(6 * 4³ + 18 * 4)
= 2√114
