• D. $f(1)=f(-1)$

Answer 1

Answer: (C)

$5km/h$ is defined, if $\frac{30}{4}km/h$ $m_1\times m_2$ $\frac{{\lambda }_1}{{\lambda }_2}$ $\sqrt{\frac{m_2}{m_1}}$ $\frac{m_2}{m_1}$ $\frac{m_1}{m_2}$ $I$ $5V$ $l_{AC}=\sqrt{2}{l}_{EF}$ and $l_{AC}=l_{EF}$ $\sqrt{2}{l}_{AC}=l_{EF}$ $l_{AD}=4l_{EF}$ and $O=\overline{X+Y}$ $O=\overline{XY}$ $O=\overline{X}.\overline{Y}$
