The range of the function f(x)=sqrt(5|x|...

The range of the function `f(x)=sqrt(5|x|-^2-6)` is
`a.(-3,\ -2)uu(2,3)` b. `[-3,-2)uu[2,3)` c. `[-3,-2]uu[2,3]` d. none of these

Text Solution

Verified by Experts

The domain of F is ` x in(−oo,2]uu[3,oo).`
For the range of F, we know that the square root
function returns non-negative numbers
so we know that the range of F is `yin[0,oo).`
