Choose a pair of functions, \( f_1 \) and \( f_2 \), that are antiderivatives of the same function on \( \mathbb{R} \).
\( f_1(x) = 3+\sin x\text{, }f_2(x)=\cos\left(\frac32\pi+x\right) \)
\( f_1(x) = 5+\sin x\text{, }f_2(x)=-\cos x \)
\( f_1(x) = \sin(x+\pi)\text{, }f_2(x)=\sin x \)
\( f_1(x) = \cos x\text{, }f_2(x)=-\cos x \)
