a.
To find: If the number 2 is the correct solution for inequality
a.
Answer to Problem 13PPE
The number 2 is solution to the given inequality.
Explanation of Solution
Given information:
The inequality
Calculation:
Solve the inequality as follows:
Thus all real number less than equal 2 are solution to this inequality. Hence 2 is the solution to the given inequality.
b.
To find: If the number 3 is the correct solution for inequality
b.
Answer to Problem 13PPE
The number 3 is not the solution to the given inequality.
Explanation of Solution
As all real number less than equal 2 are solution to this inequality. Hence 3 is not solution to the given inequality.
c.
To find: If the number −1 is the correct solution for inequality
c.
Answer to Problem 13PPE
The number −1 is the solution to the given inequality.
Explanation of Solution
As all real number less than equal 2 are solution to this inequality. Hence −1 is solution to the given inequality.
