Answer: D) y = -3 sin 8x
Explanation:
The given graph has an amplitude of 3 (A = 3) and a period of π/2 (B = 4).
Therefore, the equation of the graph is: y = 3 sin 8x Option A
Option B is a reflection of Option A, shifted π units to the left
Option C is Option A, shifted 2π units to the right
Both Options B and C are equivalent to Option A
Option D is a reflection of Option A but since there is no horizontal shift, it cannot be equivalent to Option A
