Which values from the specified set make up the solution set of the inequality? 4n< 16 ; {1,2,3,4} select all of the correct answers. a. 1 b. 2 c. 3 d. 4

You may solve this problem in two ways:

If you solve the inequality explicitly (divide both sides by 4), you get

So, if has to be stricktly less than 4, you can only choose 1, 2 and 3 as answers.

Alternatively, you can plug in all of the values you're proposed and check if the inequality holds:

If , you have , which is true.

If , you have , which is true.

If , you have , which is true.

If , you have , which is false.

So, again, only 1, 2 and 3 are solutions.
