How many rational numbers are between 0 and 1 and why?
A rational number is any number that can be expressed as a fraction. Pick any integer (n) as the denominator then the numerator can be any value between 1 and n-1, for example 1/100, 2/100, 3/100,..........98/100, 99/100. All these fractions lie between 0 and 1. The denominator therefore can be any number in the range 2 to ∞ (infinity). There are thus an unlimited number of rational numbers between 0 and 1.
How do you find range of a negative number?
The range of a negative number is the infinite interval, x < 0.
What is the range of values of a number?
A single number can have only one value and so that value is its range.
What are the steps in plotting a line graph?
There are seven steps which are: 1. Identify the variables 2. Determine the variable range 3. Determine the scale of the graph 4. Number and label each axis 5. Plot the data points 6. Draw the graph 7. Title the graph
What is the largest number minus the smallest number called?
its called the range .
What is the range of y equals 8x-3?
11
How would you determine the domain and range from a list of ordered pairs?
The domain is the set of the first number of each ordered pair and the range is the set of the second number.
How do you graph range and domain?
You do not graph range and domain: you can determine the range and domain of a graph. The domain is the set of all the x-values and the range is is the set of all the y-values that are used in the graph.
Is knowing the coordinates of the vertex of a parabola enough to determine the domain and range?
i think that the range and the domain of a parabola is the coordinates of the vertex
Domain and range of a function?
The domain of a function determines what values of x you can plug into it whereas the range of a function determines the values that are your results. Therefore, look at the y-axis if you want to determine the range of a function and look at the x-axis if you want to determine the domain.
What is the domain of the square root of x mulitplied by x-9?
To an extent, the answer depends on what the range is. The domain can be the set of complex numbers, with the range also the complex numbers. The domain can be the whole of the real numbers if the range can be complex. If the range needs to be real, then the domain must be the real numbers excluding the interval (0,9). As the range is restricted (rational, integer), the domain will also shrink.
What is the domain for y equals 5x?
It could be anything you like - counting numbers, integer, rational numbers, real number, complex numbers or any subset of these. Each domain would give rise to a different range.
How do you find y-intercept with domain and range?
Domain and range are not sufficient to determine the y intercept. For example, the domain and range for the straight line y = 2x + 3 are the whole of the real numbers. That tells you nothing about the intercept.
What is the domain of F(x)x3-2x?
The domain of x^3 - 2x is whatever you choose it to be. That will then determine the range.
Domain and range of x2?
y can be any real number more than or equal to zero --> Range x can be any real number--> Domain
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.
Can the domain and range be represented by one number?
Yes.
