Answer:

[tex]\huge\boxed{f(g(x)) = 4x^2 + 12x + 9}[/tex]

Explanation:

In its raw form, function notation essentially represents an equation with only one unknown variable, expressed in terms of another.  Thus, f(x) = x² + 7x can be expressed as

g(x) = 2x + 3

f(g(x)) = (2x + 3)²

f(g(x)) = 4x² + 12x + 9

Hope it helps :) and let me know if you want me to elaborate.
