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.

Reason: b → p can be done by reflecting across a horizontal line (flip upside‑down). Z → N can be obtained by reflecting across a suitable slanted line (a diagonal mirror). Turning 6 into 9 or an 8 into ∞ requires rotations (180° and 90°, respectively), not a single reflection.
