Q:

What is the equation of the graph below? y = sin(x/3) y=sin(3x) y =sin(0.3x) y = sin(2x/3)photomath doesn't have this to find the answer this is precalculous so 5th graders don't answer this question you will surely get this wrong or even 9th graders unless you skipped 3 grades above normal 9th grade math

A:
Answer:y = sin 3x.Step-by-step explanation:We see from the graph that y = sin 2Ο€/3 = 0.Let x = 2Ο€/3 , then substituting in y = sin 3x we gety = sin 3 * (2Ο€/3) = sin 2Ο€ = 0.
