What else can I help you with?
The set of all x-values in a relation is called the?
domain
How do you find the domain of a relation given by a set of ordered pairs?
its the x coordinate (first number) It is the set of values that the x coordinate can take.
The domain of a relation is the set of all x-coordinates from each pair?
Yes.
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.
What is an inverse relationship between x and y?
That depends on the original relation. For any relation y = f(x) the domain is all acceptable values of x and the range, y, is all answers of the function. The inverse relation would take all y values of the original function, what was the range, and these become the domain for the inverse, these must produce answers which are a new range for this inverse, which must match the original domain. IE: the domain becomes the range and the range becomes the domain. Ex: y = x2 is the original relation the inverse is y = =/- square root x Rules to find the inverse are simple substitute x = y and y = x in the original and solve for the new y. The notation is the original relation if y = f(x) but the inverse is denoted as y = f -1(x), (the -1 is not used as an exponent, but is read as the word inverse)
The set of all x-values in a relation is called the?
domain
The set of all y-values in a relation is called the?
X intercepts
Which term describes the set of all allowable input values or x-values for a relation?
The answer is most likely to be "the domain".
The set of the first numbers of the ordered pairs in a relation?
Usually the set of x values.
How do you find the domain of a relation given by a set of ordered pairs?
its the x coordinate (first number) It is the set of values that the x coordinate can take.
What is the set of all x values?
It could be the x-axis.
The domain of a relation is the set of all x-coordinates from each pair?
Yes.
X with a line over it?
The symbol "X" with a line over it is often used in mathematics to represent the average or arithmetic mean of a set of values. It is calculated by adding up all the values and dividing by the number of values in the set.
What is the definition of Domain in math?
When talking about the coordinate plain, the term domain refers to all values of "X".According to the relation and functions,Domain of a relation:If R is a relation from set A to B,then the set of all first co-ordinates of element R is called domain of RDomain of a function:Let f be the function from A to B ,set A is called the domain of f
The set of input values for a function?
The x-values in a set of points
The set of all x-coordinates of a relation is called?
The set of all the x-coordinate is called The Range. * * * * * Though more often, the x-coordinates are called the DOMAIN (and the y-coordinates are the RANGE).
What is x-bar in statistics?
The numerical average of a set of data is called x-bar. This is the sum of all values divided by the number of values.
