To find: The preference of interval notion or inequality notion to express the solution to an inequality and the reason for it. The particular circumstances for the preference.
Answer to Problem 130AYU
The preference of type of notion and the reasons are discussed below.
Explanation of Solution
Given information:
Calculation:
The solution of inequality can be represented in interval form also and inequality form also.
The interval form is used to express the finite solution of inequalities.
The inequality form of the solution of inequality is written when the solution are non finite.
If the solution is greater or less than the certain finite value then the solution is expressed in the inequality form.
Suppose the inequality is
Suppose an inequality is
Therefore, the solution of inequality is written in interval form if the solutions are finite value and the solution of inequality is written in inequality form if the solution is non finite value.
