## Answer to Problem 9E

S={2,1,0,2,4}

### Explanation of Solution

Given:

S={2,1,0,12,1,2,2,4}

Inequality,

1x12

Calculation, Let’s check for each value of S whether it satisfies the inequality or not,

For x=2 ,

1x1212121212

12 is smaller than 12 so x=2 satisfies the inequality

For x=1 ,

1x121112112

-1 is smaller than 12 So, x=1 satisfies the inequality

For x=0

1x12101212

is always greater than 12 So , x=0 satisfies the inequality

For x=12

1x1211212212

2 is not smaller than 12 So, x=12 does not satisfy the inequality

For x=1

1x121112112

1 is not smaller than 12 so, x=1 does not satisfies the inequality

For x=2

1x12121211.41120.712

0.7 is not smaller than 12 So, x=2 does not satisfies the inequality

For x=2

1x121212

12 is equals to 12 So, x=2 satisfies the inequality

For x=4

1x121412

14 is smaller than 12 So x=4 satisfies the inequality

Conclusion:

Hence the values of S which satisfies the inequality are 2,1,0,2,4
