The owner of an ice cream shop kept records of the average number of sales per month for 2019. Create a sinusoidal equation to model this information of number of sales per month.I found the maximum, minimum for this, but how can I find the period of from this table. As I already know formula to...

like how do you find domain and range off from that given equation I just don't know what to do

😂 thanks what do you do for this question: A sinusoidal function has an amplitude of 3, period of 180 degree, and a minimum at (45 degree, -2). Write the equation for the transformed cosine function.

State the domain and range for one cycle of y=cos(3(x - 45°)) +2 Show your work.

im not sure if I did it right but would the answer be 1452.4 degree +k*120 degree , 1532.4 degree +k*120 degree ??

Hey, How do you do this question: Find the first two positive x-intercepts for y= -2cos(3(x-25°)) +1

Find the first two positive x-intercepts for y= -2cos(3(x-25°)) +1 (Can someone help me for this)

Thanks

Thanksss but I am garbage at math :/

Sinusoidal Functions... Can someone help me with this. Describe the transformations that are applied to y= -4cos[2(x-30°)] +5 (State any shifts, stretches, compressions, or reflections).
