로그인 회원가입 You are solving a Korean CSAT mathematics problem. Reason carefully, but the final response must contain exactly one final answer inside \boxed{}.
For multiple-choice problems, put only one of ①, ②, ③, ④, ⑤ inside \boxed{}. For short-answer problems, put only the final integer inside \boxed{}. Do not use external tools.

The antiderivative of 𝑓 ( 𝑥 )
4 𝑥 3 − 2 𝑥 f(x)=4x 3 −2x is
𝐹 ( 𝑥 )
∫ ( 4 𝑥 3 − 2 𝑥 ) 𝑑 𝑥
𝑥 4 − 𝑥 2 + 𝐶 . F(x)=∫(4x 3 −2x)dx=x 4 −x 2 +C.
Using the initial condition 𝐹 ( 0 )
4 F(0)=4:
𝐹 ( 0 )
0 4 − 0 2 + 𝐶
𝐶
F(0)=0 4 −0 2 +C=C=4.
So 𝐹 ( 𝑥 )
𝑥 4 − 𝑥 2 + 4 F(x)=x 4 −x 2 +4. Then
𝐹 ( 2 )
2 4 − 2 2 + 4
16 − 4 + 4
F(2)=2 4 −2 2 +4=16−4+4=16.
\boxed{16}
