Given `f(x)={3-[cot^(-1)((2x^3-3)/(x^2))]forx >0{x^2}cos(e^(1/x))forx<0` (where {} and [] denotes the fractional part and the integral part functions respectively). Then which of the following statements do/does not hold good? `f(0^-)=0` b. `f(0^+)=3` c. if `f(0)=0` , then `f(x)` is continuous at `x=0` d. irremovable discontinuity of `f` at `x=0`

A

`f(0^(0-)) = 0`

B

`f(0^(+)) = 0`

C

`f(0) = 0 rArr` Continuous at x = 0

D

Irremovable discontinuity at x = 0
