The domain are the values of X that can be used and not encounter an error. In this case, no matter what you forgot, either a minus or a plus, makes the answer "all reals"

What is the domain of y equals -4x?
The domain of y = -4x is all real numbers.
What is the domain of 4x equals 13-4y?
Since your expression is a linear equation your domain would be all real numbers. This means all of the units on the x-axis.
What is 4x plus 13 equals 21?
4x+13 = 21 4x = 21-13 4x = 8 x = 2
What is the natural log of of 4x equals 13?
ln(4x)=13 4x=e^13 x=(e^13)/4
Solve x2 - 4x - 9 equals 0 by completing the square?
x2 - 4x - 9 = 0 ∴ x2 - 4x = 9 ∴ x2 - 4x + 4 = 13 ∴ (x - 2)2 = 13 ∴ x - 2 = ±√13 ∴ x = 2 ± √13

What is 4x plus 13 equals 21?
4x+13 = 21 4x = 21-13 4x = 8 x = 2
What is the natural log of of 4x equals 13?
ln(4x)=13 4x=e^13 x=(e^13)/4
What is the slope of the line 4x-5y equals 13?
4x-5y = 13 -5y = -4x+13 y = 4/5x-13/5 Slope = 4/5 or 0.8
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 domain of 3x²-4x 7?
Since it is a polynomial we know right away the domain is all real numbers.
Solve x2 - 4x - 9 equals 0 by completing the square?
x2 - 4x - 9 = 0 ∴ x2 - 4x = 9 ∴ x2 - 4x + 4 = 13 ∴ (x - 2)2 = 13 ∴ x - 2 = ±√13 ∴ x = 2 ± √13
Given the function f(x)4x-2 what is the value of the domain when the range is equal to 18?
The domain is what you DONATE to the equation. So, f(x)=4x-2. Let 18=4x-2. Add 2 to both sides. 4x=20 then divide each side by 4. x=5. That would be your answer.
What is the answer to 4x plus 3 equals 16?
4x + 3 = 16 Therefore, 4x = 13 x = 13/4 Therefore, x = 3.25
8x plus 5 equals 4x plus 13?
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
Seven less than four times a number equals 13?
Let the unknown number be x: 4x-7 = 13 Moving -7 to the other side of the equation changes it to +7: 4x = 13+7 4x = 20 Divide both sides of the equation by 4 to find the value of x: x = 5
