## Introduction to Inequality to Interval Notation Calculator

Inequality to interval notation calculator is an online tool that helps you to find the algebraic inequality equation. It also **computes the linear equation** and finds the value of x and the value of x on an interval represented on the number line.

Our inequality interval notation calculator also determines the your particular interval is open, closed, semi-open semi-closed, etc on a graph or number line.

## What is Inequality Interval Notation?

Inequality interval notation is used to **display the linear equation** solution on a number line or graph. You can separately represent the variable value or you can combine two variable values and then display them on a number line.

## Rule of Inequality Notation to Interval Notation:

Inequality Interval notation has different rules according to the inequality sign you tell whether the given interval is strictly bounded or unbounded on the graph or number line. The inequality to interval notation calculator follows some rules that are given,

### Closed Intervals

a, and b are real numbers but both **points' boundary values are not included**

$$ [ x|a \lt x \lt b ] \; \; \; \; \; \; (a,b) $$

### Open Interval

Although a, and b are real numbers both points' boundary values are included on the graph.

$$ [ x|a \le x \le b ] \; \; \; \; \; \; \; [a,b] $$

### Semi-Open Interval

Here a is the not bounded and b is the bounded interval whereas **a and b are real numbers**

$$ [x|a \le x \le b ] \; \; \; \; \; \; [a.b] $$

### Semi-Closed Interval

The semi-closed interval in the inequality to interval notation calculator is,

$$ [ x|a \lt x \le b ] \; \; \; \; \; \; \; (a,b) $$

Here b is not bounded and a is the in-bounded interval because a and b are real numbers

### Compound Interval

Compound interval is the **combination of two variables values** that may or may not be bounded interval.

$$ [ x|x \lt a \;and\; x \gt b ] \; \; \; \; \; \; \; (- \infty, a) \cup (b, \infty) $$

### Strictly Unbounded

All the real numbers in inequality interval notation calculator are bounded but their boundary points are not included on a graph or number line.

$$ [x|x \;is\;all\;real\; numbers] \; \; \; \; \; \; (-\infty, \infty) $$

### One Side Closed Interval (On the Positive Side on a Number Line)

All the real numbers are greater than a but **a is not included on a number line** or graph

$$ [x|x \gt a ] \; \; \; \; \; \; \; \; (a, \infty) $$

### One Side Closed Interval (On the Negative Side on a Number Line)

All the real numbers are less than b and b is not included on a number line or graph

$$ [x|x \lt b ] \; \; \; \; \; \; \; (-\infty, b) $$

### One Side Semi-Open Interval (On the Positive Side on a Number Line)

All the real numbers are **greater than or equal to a** and a is included on a number line or graph

$$ [x|x \ge a] \; \; \; \; \; \; \; \; \; [a, \infty] $$

### One Side Closed Interval

All the real numbers are less than or equal to b and b is included but a is not included on a number line or graph

$$ [x|x \le b] \; \; \; \; \; \; \; \; \; (-\infty, b) $$

## Evaluation Process of Inequality Interval Notation Calculator

Convert to interval notation calculator can solve one side linear equation for a specific variable or compound inequality where two linear equations are solved with one single similar variable. It is because our calculator has updated features on its server.

When you give the input value in the calculator, it will check whether the given linear equation has compound inequality or not. After checking the given equation behaviour it calculates the inequality equation as we find the usual linear equation variable value.

If the given input is in a compound inequality equation then **find the first linear equation** and then find the second linear equation. After finding the solution of both the given linear equations merge both the solutions.

Lastly, Inequality to interval notation calculator **represents the given solution** on the number line or graph as per the interval behavior that tells whether the given function is bounded or unbounded.

Let's see some examples of one-sided or compound inequality linear equations along with their solution or graphical representation for a better understanding of this concept.

## Inequality Notation to Interval Notation - Example

Inequality to internal notation examples with the solution of complete step by step explanation is given below,

### Example of a Compound Inequality

Solve the following,

$$ 5 - 3x \le -1 or 8 + 2x \le 5 $$

**Solution:**

$$ 5 - 3x \le -1 \; \; \; \; \; \; or\; \; \; \; 8 + 2x \le 5 $$

Find each inequality

$$ 5 - 3x \le -1 \; \; \; \; \; \; \; \; 8 + 2x \le 5 $$

$$ -3x \le -6 \; \; \; \; \; \; 2x \le -3 $$

$$ x \ge 2 \; \; \; \; \; \; x \le -\frac{3}{2} $$

The graphical representation of the above example is given,

### Example of One Sided Inequality

Find the following:

$$ -4 \le 3x - 7 \lt 8 $$

**Solution:**

$$ -4 \le 3x - 7 \lt 8 $$

Adding 7 to all parts:

$$ -4 + 7 \le 3x - 7 + 7 \lt 8 + 7 $$

$$ 3 \le 3x \lt 15 $$

Now divide each by 3,

$$ \frac{3}{3} \le \frac{3x}{3} \lt \frac{15}{3} $$

$$ 1 \le x \lt 5 $$

The graph of this solution is,

### Example:

Solve the following,

$$ 6x - 3 \lt 9 \; and\; 2x + 7 \ge 3 $$

**Solution:**

$$ 6x - 3 \lt 9 \; \; \; \; \; and \; 2x + 9 \ge 3 $$

$$ 6x - 3 \lt 9 \; \; \; \; \; 2x + 9 \ge 3 $$

$$ 6x \lt 12 \; \; \; \; \; \; 2x \ge -6 $$

$$ x \lt 2 \; \; \; \; \; x \ge -3 $$
