Question

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

Answer 1

• A. 1
• B. 2
• C. 3

Explanation:

The specified set is fairly limited in size, so we can simply check all the choices and see which works:

For n ∈ {1, 2, 3, 4}

... 4n ∈ {4, 8, 12, 16}

Of these values, only the first three {4, 8 12} are less than 16. (16 is equal to 16, not less than 16.)

The corresponding values of n are {1, 2, 3}.
