Find the domain and range of the function given by `f(x)=1/(sqrt(x-[x]))`

Text Solution

Verified by Experts

For the square root, `x-[x]>=0` and `x-[x]!=0`. So, `x-[x]>0` and `x>[x]`.
So `x in R-{I}`. Hence, domain : `x in R-{I}`.
Range: `0<={x}<1`
`=1< frac{1}{x} < oo`
`=1< frac{1}{sqrt(x)}< oo`.
