An interval is a collection of Real numbers. The table below lists nine types of intervals used to describe subsets of real numbers. X x 4 displaystyle xxge 4 xx 4 which translates to all real numbers x such that x is greater than or equal to 4.

27 - Use interval notation to indicate all real numbers. Using interval notation we can describe each of these inequalities separately. In parts ad use two inequalities to describe the interval.

If ba is positive then we write either aaread b is greater than a. The real numbers can be ordered by size as follows. The closed interval ab represents the set of all real numbers between a and b including a and b.

In general all the arithmetic operations can be performed on these numbers and they can be represented in the number line also. Work with a partner. The third method is interval notation in which solution sets are indicated with parentheses or brackets.

8x 2x - 1 -1 is the domain 1. Other examples of intervals are the set of numbers such that 0 x 1 the set of all real numbers R displaystyle mathbb R the set. A -92 B -29 C -291 D -29 E none of these 2 2 For fx -x2 3x 1 compute fx 1.
