MCQ (Single Correct Answer)

-0.25

Let f be derivable in [0, 1], then

there exists $$c \in (0,1)$$ such that $$\int\limits_0^c {f(x)dx = (1 - c)f(c)} $$

there does not exist any point $$d \in (0,1)$$ for which $$\int\limits_0^d {f(x)dx = (1 - d)f(d)} $$

$$\int\limits_0^c {f(x)dx} $$ does not exist, for any $$c \in (0,1)$$

$$\int\limits_0^c {f(x)dx} $$ is independent of $$c,c \in (0,1)$$

$${\pi \over 2}$$
