What do the letters in mathematics stand for?
Some letters such as e is a number, and i stands for imaginary number. But most letters are variables. x is a common variable. A variable is basically a number that you don't know so you just call it x.
What is the variable for the domain called?
The variable for the domain is typically referred to as the "independent variable." In a mathematical function, the independent variable represents the input values for which the function is defined, while the corresponding output values are determined by the dependent variable. For example, in the function ( f(x) = x^2 ), ( x ) is the independent variable from the domain.
How is the word domain used in algebra?
Domain is used to refer to the x (or the independent variable).
Domain and range?
In algebra, the domain consists of all possible values for the x variable that could make the function work. The range is all of the possible values of the function, using each number in the domain.
Does anything squared equal negative on and that number squared?
If I understand the question correctly, the answer is not in real numbers. But in the complex domain, there is the imaginary number i is such that i2 = -1. And so, for any positive x, [i*sqrt(x)]2 = i2*x = -1*x = -x, which is negative.

Is the x or the y the domain in a function?
x is a letter often used as a variable. It can be in the range or the domain. However, in elementary algebra, the variable x is most often used for the domain and f(x) =y for the range.

X x x is always a positive number?
No. Not is x = 0 or if it an imaginary number.
What is the range of fx equals 2x - 5?
Domain is the number of x values that can be used and not cause an imaginary result. Range is the number of the y values that result. In f(x)=2x-5 the range is all real numbers.
What is domain math term?
Domain, in math terms, is the set of possible x values. This changes with your function. f(x)=x, for example, has a domain of negative infinity to infinity. However, f(x)=squareroot of x can only be positive, as otherwise it would go to imaginary numbers. Hence, its domain is 0 to inifinity.
What is the domain of the function of fx5x?
f(x)=5x Domain is any number for x that will provide a real number for f(x). In this function, x can be any real number, and f(x) will be a real number. Thus domain is all real numbers.
Is there a case where a value a value cannot be part of a domain?
A number that produces a new kind of number would limit the domain. For example if I was taking a square root I couldn't use a negative value with producing an imaginary number. In a quadratic equation there are times when you won't make a negative number like y^2=x. x will never be negative because the square of any real number is a positive.
What letter could never be used as a variable?
You can use any letter as a variable, although they can get confused with symbols like t with +, i with imaginary, and x with multiplication.
