Disagree with Justin, because 12 is also included in the solution as we can see on the number line on 12 there is a bold sign.
What is inequality?
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
The inequality is:
f ≥ 12
In interval notation
f ∈ [12, ∞)
12 is also included in the solution as we can see on the number line on 12 there is a bold sign.
Thus, disagree with Justin, because 12 is also included in the solution as we can see on the number line on 12 there is a bold sign.
