The function f(x)=(4-x^2)/(4x-x^3) a)...

The function `f(x)=(4-x^2)/(4x-x^3)` a)discontinuous at only one point b) discontinuous exactly at two points c)discontinuous exactly at three points d) none of these

Text Solution

Verified by Experts

`f(x) = (4-x^2)/(4x-x^3 )`
`= (4 -x^2)/(x(4- x^2))`
`f(x) = (4-x^2)/(x(2-x)(2+x))`
`x= 0, 2,-2`
at `x=0,2,-2`
so, f(x) is discontinuous
