Is the standard square root function bounded?
If the range is the real numbers, it has a lower bound (zero) but no upper bound.
Why root 2 is smaller than 3 root 4?
This is because the square root function, with the range defined as the non-negative real numbers, is monotonic increasing throughout.
Is the inverse of a quadratic function is square root function?
yes
What does domain and estimate the range mean in math?
"Domain" means for what numbers the function is defined (the "input" to the function). For example, "x + 3" is defined for any value of "x", whereas "square root of x" is defined for non-negative "x". "Range" refers to the corresponding values calculated by the function - the "output" of the function. If you write a function as y = (some function of x), for example y = square root of x, then the domain is all possible values that "x" can have, whereas the range is all the possible values that "y" can have.
Is the square root of 5 a function?
Yes, if your equation is f(x) = sqrt5(x). The square root is also a function itself, if that's what you mean.
