ANSWER
Option B
and
Option D.
EXPLANATION
The graph of the function has an amplitude of 2 and a period of
[tex] \frac{2\pi}{3} [/tex]
Choose all the equation that has an amplitude of 2 and a period of
[tex]\frac{2\pi}{3} [/tex]
These are:
[tex]y = 2 \sin3(x - \frac{2\pi}{3} ) [/tex]
and
[tex]y = 2 \sin(3x) [/tex]
The second and the last options are correct.
