If the range is the real numbers, it has a lower bound (zero) but no upper bound.
yes
Yes, if your equation is f(x) = sqrt5(x). The square root is also a function itself, if that's what you mean.
Standard deviation = square root of variance.
Let's illustrate with an example. The square function takes a number as its input, and returns the square of a number. The opposite (inverse) function is the square root (input: any non-negative number; output: the square root). For example, the square of 3 is 9; the square root of 9 is 3. The idea, then, is that if you apply first a function, then its inverse, you get the original number back.
To calculate the inverse of a square root function, you can start by expressing the square root function as ( y = \sqrt{x} ). To find the inverse, you swap ( x ) and ( y ), resulting in ( x = \sqrt{y} ). Then, solve for ( y ) by squaring both sides, giving you ( y = x^2 ). Thus, the inverse of the square root function is the square function, ( f^{-1}(x) = x^2 ).
The standard deviation of a normal deviation is the square root of the mean, also the square root of the variance.
It is the "square root." This is the opposite function (n1/2) of the square (n2).
yes
The standard form of a complex number is a+bi. So the standard form of the negative square root of 5i is 0-√(5i).
The square of the standard deviation is called the variance. That is because the standard deviation is defined as the square root of the variance.

Standard deviation is the square root of the variance.

This is typically done by importing math.h, and calling the sqrt function.
