Simply sub in the points from each set and solve to see if they are greater than or equal to 2
2*1-4=-2 NO
2*2-4=0 NO
2*3-4=2 YES

Therefore, any numbers 3 or above make up the solution; the answer is {3, 4}

By substituting the values into the inequality, the set of true values for which the inequality exists is {3, 4}

Given the inequality :

  • 2b–4≥2

Substituting the values into the expression :

Using 1 :

2(1) - 4 = 2 - 4 = -2

-2 2 (false)

Using 2 :

2(2) - 4 = 4 - 4 = 0

0 ≥ 2 (false)

Using 3 :

2(3) - 4 = 6 - 4 = 2

2 ≥ 2 (True)

Using 4 :

2(4) - 4 = 8 - 4 = 4

4 ≥ 2 (True)

Hence, the set of true values for which the inequality exists is {3, 4}
