If the whole number line is shaded for (x), what is the solution?

Answer and explanation

Correct answer: \(x\in \mathbb{R}\)

A shaded entire number line means that negative numbers, zero, and positive numbers are all included in the solution set. Hence, \(x\in \mathbb{R}\) is correct. \(x>0\) and \(x<0\) represent only one part of the number line, not the whole line. Exam tip: when the complete number line is shaded, the solution set is all real numbers.
