2) Constraints can be used to model different variables that cannot equal zero. They can be used in many different cases. For example, modeling money or a ball being dropped.
1. When you graph nonlinear equations, you can find the points of the intersection where you will see where the functions intersect. It will make it easier to find the possible solutions. 2. Constraints also can be known as imitations are needed in model real-world situations. For example, when projecting budgets in business or also could be restrictions in time, space, or money.
Step-by-step explanation: Because the complement of a set include all of the elements not included in the indicated set. I hope I'm making some sense. :)
