Explain when the solution set of an inequality will be the empty or the set of all real numbers, show an example of each.
Answer to Problem 59HP
Explanation of Solution
Given:
Concept Used:
We can get inequalities that are false for any variable. These inequalities have no solution.
It's possible for inequalities to have no solution If you come across an inequality that indicates information that is not true, then the inequality has no solution.
Let's look at the example:
There is no way that an absolute value can be less than or equal to a negative number. By definition, absolute values are greater than or equal to 0.
We can say that this inequality has no solution.
Example 2:
Here we get a false statement because − 8 is not less than − 11. This means the inequality has no solutions.
We can also get inequalities that are true for any variables. These have infinite number of solutions.
Example 3:
Here we get a true statement. 3 is greater than or equal to 3. So we know this inequality`s solution is all real number or infinite solutions. No matter what number you put in for p , you get a true statement.
Calculation:
Thus,
