What is the domain of a square root function with an endpoint at 4 5?
There can be no possible answer because the point (4, 5) is not on a square root.
What is the domain of the square root of x plus 9?
{ x | x is greater than or equal to -9 . } is the domain of the real function defined by this formula.
What does it mean two operations that undo each other?
Two operations are said to undo each other if each operation is the inverse (NOT reciprocal) of the other. Often the domain and range of the operations will need to be restricted so that the inverse exists. Some examples: Addition and subtraction. Multiplication and division. Sine of an angle and arcsine of a ratio (similarly the other trig ratios). Square and square root. Exponentiation and logarithm. Thus 3-squared is 9 and the [principal] square root of 9 is 3. If the range of the square root function is not restricted to non-negative roots, then the square root of 9 could also be -3.
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.
What is the range of the square root function?
The answer depends on the domain. If the domain is non-negative real numbers, then the range is the whole of the real numbers. If the domain is the whole of the real numbers (or the complex plane) , the range is the complex plane.
What are the domain And range for the square root function?

What is the domain of a square root function with an endpoint at 4 5?
There can be no possible answer because the point (4, 5) is not on a square root.
What is the domain of the function f x x 2 plus 4?
The domain of the function f (x) = square root of (x - 2) plus 4 is Domain [2, ∞)
What is the domain of the square root of x plus 9?
{ x | x is greater than or equal to -9 . } is the domain of the real function defined by this formula.
Is x equals the square root of y-4 a function?
The square root operation is not a function because for each value of y there can be 2 values of x - the principal square root and its negative. This can only be rectified by limiting the range of the opearation to the principal or positive square root. Furthermore, it also depends on the domain of the function. If y<4 then the square root is not defined within Real numbers. So, for y ≥ 4, x = +sqrt(y-4) is a function.
What is Domain of the Function?
The domain of a function is the set of numbers that can be valid inputs into the function. Expressed another way, it is the set of numbers along the x-axis that have a corresponding solution on the y axis.
How do you determine the domain and range of relations and functions?
Some functions are only defined for certain values of the argument. For example, the the logarithm is defined for positive values. The inverse function is defined for all non-zero numbers. Sometimes the range determines the domain. If you are restricted to the real numbers, then the domain of the square root function must be the non-negative real numbers. In this way, there are definitional domains and ranges. You can then chose any subset of the definitional domain to be your domain, and the images of all the values in the domain will be the range.
How do you find the domain of a function?
to find the domain first check all the possibilities of the denominator attaining a value of zero then if the function has any thing inside a square root, the expression inside the root must be always greater than or equal to zero.If the square root is in the denominator then the expression inside must be just greater than zero but not equal to zero.

What is the domain of the square root of 3x 3?
Assuming you mean 3x3: If you work with real numbers, anything under the square root sign must be non-negative, so if you solve the inequality: 3x3 >= 0 for x, you get all valid values of x for this function, in other words, the domain.
