An open interval, usually written as (2, 4) is any number between 2 and 4 but excluding the two end points. Another way of writing it is {x : 2 < x < 4}.

A closed interval includes both end points and a semi-open or semi-closed includes one but not both.

What is a interval in math?

In mathematics, an interval is a set of numbers that contains all numbers between any two numbers in that set. Intervals can be classified as open (excluding the endpoints), closed (including the endpoints), or half-open (including one endpoint but not the other). For example, the interval [a, b] is closed and includes the endpoints a and b, while (a, b) is open and does not include them. Intervals are commonly used to represent ranges of values on the number line.

What are math extremes?

In short, math extreme is the highest (or lowest) value of a math function on an interval (a,b). For example, function y=x2 has minimum (extreme) for x=0 on interval (minus infinity, plus infinity). Similarly, function y=-x2 has maximum (extreme) for x=0 on the same interval. Some functions have multiple extremes, which are called local extremes, but this is enough for basic understanding of the principle.
