The composite function G(F(x)) = x² + 4 is formed with these following original functions:
D. F(x) = x² and G(x) = x + 4.
The composite function of f(x) and g(x) is given as follows:
[tex](f \circ g)(x) = f(g(x))[/tex]
For g of f(x), we have that:
[tex](g \circ f)(x) = g(f(x))[/tex]
For this problem, we have that:
G(F(x)) = x² + 4.
Which is possible with option D, as:
[tex]G(F(x)) = G(x^2) = x^2 + 4[/tex]
