The whole of the real line, or even the whole complex plane.
sqrt(x) Range: {0,infinity)
Domain is greater than or equal to zero. same with range
There are infinitely many of them. They include square root of (4.41) square root of (4.42) square root of (4.43) square root of (4.44) square root of (4.45) square root of (5.3) square root of (5.762) square root of (6) square root of (6.1) square root of (6.2)
This is because the square root function, with the range defined as the non-negative real numbers, is monotonic increasing throughout.
A principal square root is any square root that's answer is positive, and a perfect square root is a square root that's answer is an integer.

sqrt(x) Range: {0,infinity)
Range, standard deviation, variance, root mean square, interquartile range
In Real numbers the range is [0,1] - or it could be [-1, 0].
Domain is greater than or equal to zero. same with range

The range of a power station is worked out by multiplying 1.25 by square root of the mast size
17-(2x8)=1
It's not a square if it has no root. If a number is a square then, by definition, it MUST have a square root. If it did not it would not be a square.
