Given f(x) = 6x + 9 and g(x) = X^4, choose
the expression for (fºg)(x).

Answer:
(fºg)(x) = [tex]6x^{4}+9[/tex]
Step-by-step explanation:
We have been given the following two functions;
f(x) = 6x + 9
g(x) = X^4,
We are then required to determine the expression for (fºg)(x). (fºg)(x) denotes a composite function f[g(x)] which is obtained by
substitute g(x) in place of x in f(x)
(fºg)(x) = 6[g(x)] + 9
(fºg)(x) = 6X^4 + 9
