Question

What is the equation of the graph below

Answer 1

Answer:

The answer is B) y = Sin(3x)

Step-by-step explanation:

In order to find this, you need to look for how long it takes the period to repeat. This means other than the origin, we need to find the next place that the graph hits y = 0. In this case, it is at 2$\pi$/3. Since Sin2$\pi$ = 0, we need what is inside of the parenthesis to equal 2$\pi$.

The only thing that you could multiply 2$\pi$/3 by to get 2$\pi$m is 3. Therefore, we must have 3x in the original equation.
