Answer:

[tex]h(x) = x^{3}[/tex]

Step-by-step explanation:

[tex]f(x) = (8 \times x^{4}- 3)^{3}[/tex] ------------(1) (given)

[tex]g(x) =(8 \times x^{4}- 3)[/tex] -------------(2) (given)

so,

f(x) = h(g(x)) (given)

    = [tex](g(x))^{3}[/tex]-----(from (1) and (2))

⇒[tex]h(k) = k^{3}[/tex]-----(taking g(x) = k)

⇒[tex]h(x) = x^{3}[/tex] is the function.
