If the number line is shaded from (0) to (6), with (0) open and (6) closed, what is true about (x=0)?

Answer and explanation

Correct answer: (x=0) is not included in the solution set

An open circle on a number line means that endpoint is excluded. Since the circle at 0 is open, (x=0) is not in the solution set. The shaded interval can be written as \(0<x\leq 6\); 6 is included because it has a closed circle. Exam tip: use < or > for an open circle and \(\leq\) or \(\geq\) for a closed circle.
