Question

Which of the following changes could be achieved by reflection? Answer 1, 2, 3, or 4.

turning a 6 into a 9
turning a b into a p
turning an 8 into an infinity sign ∞

turning a Z into an N
(1 point)

Answer 1

2 and 4.

- b → p: a vertical reflection (flip across a horizontal line) turns b into p.
- Z → N: a reflection across the diagonal line y = x (or that 45° line) turns Z into N.

6 → 9 is a 180° rotation, and 8 → ∞ is a 90° rotation — neither is a single reflection.
