We need to find the   x values (if any) that make  the inside function < 0

A graph seems best [ IMHO  !!! ]

Look at the graph here : https://www.desmos.com/calculator/im64nbdu1v

The function under the radical is always > 0 for all x values....so...the domain is ( -inf, inf)

And the graph of the function itself, here, https://www.desmos.com/calculator/xytn5zb5ky

Shows the range to be   ( ≈ 111.504, inf )
