What is the domain and range for y equals x squared minus 4?

You can define the domain as anything you like and that will determine the range. Or, you can define the range as anything you like and that will determine the domain. For example: domain = {1, 2, 3, 4, ... } then range = {-3, 0, 5, 12, ... } or range = {1, 2, 3, 4, ... } then domain = {sqrt(5), sqrt(6), sqrt(7), sqrt(8), ...}. There is, of course, no need to restrict either set to integers but then it was easier to work out one set from the other.


What is the domain and range of y equals x cubed?

The Domain and Range are both the set of real numbers.


How do you find the range and domain of a graph function?

Assuming the standard x and y axes, the range is the maximum value of y minus minimum value of y; and the domain is the maximum value of x minus minimum value of x.


What is x y 12 with domain and range?

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2). However, the domain and range are not defined in an absolute way. You can choose any domain that you like (within reason) and the definition of the range will follow. Or conversely. Suppose the equation is x = y + 12 Then you can, for example, define the domain (values of x) as the set of numbers 1, 3, and 97.2. The range, in that case will be -11, -9 and 85.2

How do you find the domain and range of f of x equals x squared minus 3x minus 10?

The domain is what you choose it to be. You could, for example, choose the domain to be [3, 6.5] If the domain is the real numbers, the range is [-12.25, ∞).


What is the domain and range of y equals the square root of four minus x squared?

The domain and the range depends on the context. For example, the domain and the range can be the whole of the complex field. Or I could define the domain as {-2, 1, 5} and then the range would be {0, 3, -21}. When either one of the range and domain is defined, the other is implied.


Is y equals x squared -4x plus 3 a domain or range?

Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.


What is the range of the equation y equals X squared plus 6?

The answer depends on the domain for x. For example, if the domain is x = 7, then the range is 55. If the domain is all Real numbers, then the range is y >= 6.
