AP.CALC: FUN‑3 (EU), FUN‑3.C (LO), FUN‑3.C.1 (EK)

A composite function can be written as w, left parenthesis, u, left parenthesis, x, right parenthesis, right parenthesis, where u and w are basic functions.

Is g, left parenthesis, x, right parenthesis, equals, left parenthesis, 2, x, squared, plus, 5, x, right parenthesis, tangent, left parenthesis, x, right parenthesis a composite function? If so, what are the "inner" and "outer" functions?

(Choice A)
