it's the third choice because of your radius like how it's 2πR^2

Answer:  [tex]\bold{D)\quad y = 2sin(3x)}[/tex]

Step-by-step explanation:

[tex]\text{The standard form of a sine equation is: y=A sin(Bx - C) + D}\\\\\bullet\text{A = amplitude}\\\\\bullet\text{Period = }\dfrac{2\pi}{B}\\\\\bullet\text{Phase Shift = }\dfrac{C}{B}\\\\\bullet\text{D = vertical shift (up if positive, down if negative)}[/tex]

In the given graph,

  • A (amplitude) = 2
  • P (period) = [tex]\dfrac{2\pi}{3}[/tex] --> B = 3
  • Phase Shift [tex]\bigg(\dfrac{C}{B}\bigg)[/tex] = 0  --> C = 0
  • D (vertical shift) = 0

[tex]\implies \large\boxed{y = 2sin(3x)}[/tex]

see graph below for verification
