The range of the function f(x)=x/(|x|) i...

The range of the function `f(x)=x/(|x|)` is
`R-{0}` b. `R-{-1,1}` c. `{-1,1}` d. none of these

Text Solution

Verified by Experts

Given, `f(x) = x/|x|`
We know that, `|x| = -x` in `(-oo, 0)`
and `|x| = x` in` [0, ∞)`
So, ` f(x) = x / (-x)= -1` in `(-oo, 0) ` ...
