A sinusoidal function whose frequency is 16π, the maximum value is 12, the minimum value is  −6   has a y-intercept of 3.

Which function could be the function described?

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

f(x)=3sin(6πx)+9

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

f(x)=9sin(6πx)+3

A cosine function has a period of 5, a maximum value of 20, and a minimum value of 0. The function is not a reflection of its parent function over the x-axis.

Which function could be the function described?

f(x)=−10cos(2π5x)+10

f(x)=10cos(2π5x)+10

f(x)=10cos(5x)−10

f(x)=−10cos(5x)+10
