The uppercase ‘r’ symbol: It represents the set of all real numbers and is commonly used in algebra and calculus. For example, if we need to express a solution in a mathematical equation that contains variables, we would use the symbol ‘r’ to represent any real number as long as it satisfies the equation.The collection of the real numbers is complete: Given any two distinct real numbers, there will always be a third real number that will lie in between. the two given. Example 0.1.2: Given the real numbers 1.99999 and 1.999991, we can find the real number 1.9999905 which certainly lies in between the two.A point on the real number line that is associated with a coordinate is called its graph. To construct a number line, draw a horizontal line with arrows on both ends to indicate that it continues without bound. Next, choose any point to represent the number zero; this point is called the origin. Figure 1.1.2 1.1. 2.Real Numbers Definition. Real numbers can be defined as the union of both rational and irrational numbers. They can be both positive or negative and are denoted by the symbol “R”.

Here R is set of real numbers.We can embed Q into R by identifying the rational number r with the equivalence class of the sequence (r,r,r, …). Comparison between real numbers is obtained by defining the following comparison between Cauchy sequences: (x n) ≥ (y n) if and only if x is equivalent to y or there exists an integer N such that x n ≥ y n for all n > N. One way to include negatives is to reflect it across the x axis by adding a negative y = -x^2. With this y cannot be positive and the range is y≤0. The other way to include negatives is to shift the function down. So y = x^2 -2 shifts the whole function down 2 units, and y ≥ -2. ( 4 votes) Show more...

Introducing intervals, which are bounded sets of numbers and are very useful when describing domain and range. We can use interval notation to show that a value falls between two endpoints. For example, -3≤x≤2, [-3,2], and {x∈ℝ|-3≤x≤2} all mean that x is between -3 and 2 and could be either endpoint.For each real number \(x\), \(x^2 > 0\). The phrase “For each real number x” is said to quantify the variable that follows it in the sense that the sentence is claiming that something is true for all real numbers. So this sentence is a statement (which happens to be false).The closure of $\mathbb{Q}$ is all of $\mathbb{R}$: every real number is the limit of a sequence of rationals, so every real number lies in the closure of $\mathbb{Q}$. Since $\mathbb{Q}$ does not equal its closure, it is not closed.DEFINITIONS In all the definitions below, a and b represent arbitrary real numbers.
