Advanced Math practice question

Answer: 2

For x ≠ 1, r(x) = x + 1. The missing point is at x = 1, where the line would give y = 2.

Common wrong answers

If you answered 0

0 comes from evaluating x² − 1 at x = 1 without simplifying first.

If you answered 1

1 is the x-coordinate of the missing point.

If you answered -1

−1 comes from a sign error in x + 1.
