At which x-values does the graph y = |x + 1| - 2 cut the x-axis?

Answer and explanation

Correct answer: x = -3 and x = 1

The governing concept is finding x-intercepts by setting the output y equal to zero. For the graph y = |x + 1| - 2, put 0 = |x + 1| - 2, which gives |x + 1| = 2. A modulus equation |u| = 2 has two cases: u = 2 or u = -2. Therefore x + 1 = 2 gives x = 1, and x + 1 = -2 gives x = -3. Both values satisfy the original equation, so the graph cuts the x-axis at x = -3 and x = 1. Hence option B is correct. The other choices arise from ignoring the negative modulus case, changing the sign incorrectly, or shifting the constants improperly.
