What is the domain and range of y equals x?
The domain of a function represents the set of x values and the range represents the set of y values. Since y=x, the domain is the same as the range. In this case, they both are the set of all real numbers.
What is date of birth 01102007 in roman numerals?
1-10-2007 = i-x-mmvii They are more preferable in capital letters but they both have the same values.
Is -2x the same as x-2?
No, -2x is not the same as x - 2. The expression -2x represents the product of -2 and x, while x - 2 represents the value of x decreased by 2. They are different algebraic expressions and will yield different values for most values of x.
When two expressions are the same does any one know the term for that?
If they are the same for only some values of the variables, they form an equation. If they are the same for all values of the variables, they form an identity. For example, (x + y)2 = x2 + y2 is an equation which is true if x = 0 or y = 0 (or both), while (x + y)2 = x2 + 2xy + y2 is always true and so is an identity.
What is the difference between domain and range in math?
Domain is the spectrum of values on the x-axis. Domain will be which x-values can be plugged into that equation and give an answer. Range is the same thing, but y-values. On the graph it will be the y-values that are included in the graph.
Can two different x values have the same Y value?
Yes, depending on the function. For example, in the function y = x squared, for x-values of both 2 and -2 you get the same y-value.
Which quadrants do the x-axis and y-axis have the same sign?
Quadrants I and III. In Quadrant I, the values are both positive. In Quadrant III, the values are both negative.
When is true that absolute value of x plus y equals sum of their individual absolute values?
When 'x' and 'y' both have the same sign.
What is the domain and range of y equals x?
The domain of a function represents the set of x values and the range represents the set of y values. Since y=x, the domain is the same as the range. In this case, they both are the set of all real numbers.
Is a function a relation if and only the x-values do not repeat in a given set?
No. If an x-value is repeated but both values have the same image, you can still have a valid function. x values not repeating is not sufficient if there is no image. For example, consider 1/x and the domain as the integers -3, -2, -1, 0, 1, 2, 3. None of the x values repeats but there is no functional relationship because 1/x is not even defined for x = 0.
How do you find the quadrant number of a point?
If the points have both positive y-values and x-values it is quadrant 1 If the points have a negative x-value and a positive y-value it is quadrant 2 If the points have both negative y-values and x-values it is quadrant 3 If the points have a positive x-values and a negative y-value it is quadrant 4
Which expression has the same value as tan(-x) for all values for x?
tan(-x) = -tan(x)
What is date of birth 01102007 in roman numerals?
1-10-2007 = i-x-mmvii They are more preferable in capital letters but they both have the same values.

Which is the first quadrant in a coordinate grid?
The top right one... it is the first because it is where both the x-value and y-values are positive. The second quadrant is the top left. The x-values are negative and the y-values are postive. The third quadrant is the bottom left. The x-values are negative and the y-values are negative. The fourth quadrant is the bottom right. The x-values are positive and the y-values are negative.
What is the value of x plus y?
The value of x + y is indeterminate. You need the values of both x and y to determine x + y.
