If \(x=-1\), which of the following inequalities is true?

Answer and explanation

Correct answer: \(x\le -1\)

Substituting \(x=-1\) in option B gives \(-1\le -1\), which is true because equality is included. Option A gives the false statement \(-1<-3\), and options C and D are also false for \(x=-1\). In an exam, substitute the given value directly and check carefully whether equality is included in the inequality sign.
