Answer:
see explanation
Step-by-step explanation:
The standard form of the sine wave function is
y = a sin (bx + c) + d
where amplitude = | a |, period = [tex]\frac{2\pi }{b}[/tex]
phase shift = - [tex]\frac{c}{b}[/tex] and d is the vertical shift
Here a = - 2, b = 3 and c = - π
Hence
amplitude = | - 2 | = 2
period = [tex]\frac{2\pi }{3}[/tex] and
phase shift = - [tex]\frac{-\pi }{3}[/tex] = [tex]\frac{\pi }{3}[/tex]
