At which \(x\)-values do the graphs of \(y=|x+1|\) and \(y=5\) intersect?

Answer and explanation

Correct answer: \(x=-6\) और \(x=4\)

At an intersection, the two graphs have the same \(y\)-value, so \(|x+1|=5\). Thus, \(x+1=5\) or \(x+1=-5\), giving \(x=4\) or \(x=-6\). Therefore, option A is correct. Exam tip: for \(|u|=a\) with \(a>0\), always consider both cases \(u=\pm a\).
