As you see in the picture, there are two lines that could maybe represent two linear functions. However, this is not true because of the solid point and the hollow point. This is an inequality equation that has points of discontinuity.
Points of discontinuity are breaks in the graph that are a result of an undefined point when the f(x) is substituted with a point of x that is not part of the solution. So, technically, the graph is made from one rational expression.
So, when it says f(-2), this is the y-value at x=-2. That means f(-2)=2, f(0)=3 and f(4)=-1. Specifically, there are two points at x=0, but we take the solid point only.

Answer:
20 Students
Step-by-step explanation:
If there is 1 chaperone for every 4 students, and there are a total of 5 chaperones on the trip, you can use this information to know that..
If there are 5 chaperones and 4 students for each chaperone, that would give you 20 students!
