Question 10 • Mathematics II
At an intersection, both equations have the same y-value, so set them equal: x² + 2x − 3 = x − 1. This gives x² + x − 2 = 0, which factors as (x + 2)(x − 1) = 0, so x = −2 or x = 1. Substituting into y = x − 1 gives the points (−2, −3) and (1, 0), which matches choice C.
