举一反三
- 若f(x)+f(-x)=0, 则[img=95x39]17da608af452d96.jpg[/img]. 若f(x)=f(-x), 则 [img=170x38]17da60541207426.jpg[/img]
- 设[img=28x19]17da41b38e91a03.jpg[/img]为可导函数,则[img=63x37]17da426f632f014.jpg[/img]的导数是( ) A: f(x) B: f(x)+C C: f '(x) D: f '(x)+C
- 设f(x)=[img=15x18]17da42685cb8d76.jpg[/img],则f【f'(x)】=
- 设X的密度函数为f(x)，分布函数为F(x)，且f(x)是偶函数，则有 A: [img=235x53]1803b3ba8e4e24a.png[/img] B: [img=248x66]1803b3ba9822ce1.png[/img] C: F(−x)= F(x) D: F(−x)=2F(x)−1
- 设随机变量X的概率密度为f(x)，则f(x)一定满足( ). A: 0≤f(x)≤1 B: [img=183x53]1803b451bb3373a.png[/img] C: [img=133x51]1803b451c807078.png[/img] D: f(+∞)=1
