There is more than one notation, but the open interval between a and b is often written (a,b) and the closed interval is written [a,b] where a and b are real numbers. Intervals may be half open or half closed as well such as [a,b) or (a,b]. For all real numbers, it is (-infinity,+infinity), bit use the infinity symbol instead (an 8 on its side).

What does interval mean in math terms?
In math, an interval is a set of real numbers with the property that any number that lies between two numbers in the set is also included in the set.
The interval of a graph is the difference between any two numbers on the scale?
Yes, the interval of a graph is the difference between any two consecutive numbers on a scale.For example, if the scale read: 2,4,6,8,10 then you could do 4-2, 6-4, etc. to find the interval. (which is 2)

What is a continuous random variable?
In the simplest setting, a continuous random variable is one that can assume any value on some interval of the real numbers. For example, a uniform random variable is often defined on the unit interval [0,1], which means that this random variable could assume any value between 0 and 1, including 0 and 1. Some possibilities would be 1/3, 0.3214, pi/4, e/5, and so on ... in other words, any of the numbers in that interval. As another example, a normal random variable can assume any value between -infinity and +infinity (another interval). Most of these values would be extremely unlikely to occur but they would be possible. The random variable could assume values of 3, -10000, pi, 1000*pi, e*e, ... any possible value in the real numbers. It is also possible to define continue random variables that assume values on the entire (x,y) plane, or just on the circumference of a circle, or anywhere that you can imagine that is essentially equivalent (in some sense) to pieces of a real line.
The term used to a way of writing the set of all real numbers between endpoints is?
Interval Notation
Write an interval notation?
Interval notation is a method of writing down a set of numbers. An example of this is all numbers that are greater than five.Ê
What is interval notation?
Interval notation uses the symbols [ and ( to indicate closed an open intervals. The symbols can be mixed so that an interval can be open on one side and close on the other. Given two real numbers, a, b we can have (a,b) which is the interval notation for all numbers between a and b not including either one. [a,b) all numbers between a and b including a, but not b. (a,b] all numbers between a and b including b, but not a. [a,b] all number between a and b including a and b.
Which interval notation represents the set of all real numbers from -3 to 5 including 5 but not including -3?
It is (-3, 5].
Which Interval notation represents the set of all real numbers Greater than 2 and less than or equal?
The answer to this is 2, and 0.
Which interval notation represents all real number greater than -3?
The interval (-3, infinity).
The real numbers between 1 and 6?
The real numbers between 1 and 6 form an interval on the number line. This interval is denoted as (1, 6), where the parentheses indicate that the endpoints 1 and 6 are not included. In interval notation, this set can be written as {x | 1 < x < 6}. This set includes all real numbers greater than 1 and less than 6.
Which interval notation represents the set of all real numbers from negative 3 to 5 but not including negative 3?
(-3, 5] = {x : -3 < x ≤ 5}
What is the real number interval?
It is the space between two real numbers.
How do you do interval notation?
-4
How do I write an interval notion and graph it...it is a set of real numbers that would be less than or equal to -4?
For an interval of numbers, two types of brackets are used, [] and (), the first signifies that interval includes the number before/after it and the latter indicate the interval includes everything upto that value.e.g.[0,2] indicates an interval of all real numbers from 0 to 2 including those numbers(-1,6) indicates an interval of all real numbers between -1 and 6 but not -1 and 6 themselves[5,12) indicates an interval of all real numbers from 5 upto but not including 12and (-9,-2] indicates an interval of all real numbers from -2 down to but not including -9.so, an interval of real numbers less than and equal to -4 would be (-­∞,-4], we use a ( for -∞ as, obviously, infinity can never be reached.To graph line intervals, we use a solid line along the interval and use filled circles, •, to signify that the point it is on is included in the interval, and empty circles, ○, to signify the point it is on is not included in the interval. So an interval of [5,12) would be drawn like this,•--------------------○5 6 7 8 9 10 11 12the drawing for (-­∞,-4] would simply be a straight solid line from the end of the negative side of the number line upto -4 with a • to show that -4 is included.
