A sinusoidal function whose frequency is 3, maximum value is 12, minimum value is −6 has a y-intercept of 3.

Which function could be the function described?

f(x)=9sin(6πx)−6

f(x)=9sin(6πx)+3

f(x)=9sin(3x)+3

f(x)=9sin(x/3)−3

I think it is B possibly

it is either b or c due to the fact that (0, 3) is on the graph, and since the frequency is 3, the period is 1/3, and since it is 2pi/(the coefficient of x inside the sin function), then only \(\boxed{B}\) satiesfies it, because the coefficient is 6pi, and you get 2pi/6pi or 1/3.
