3. The table below shows the highest daily temperatures (in degrees Fahrenheit) averaged over the month for the city of Binghamton, NY. Assume Jan represents t = 1. Month Мay Jan Feb Mar Apr Jun Jul Aug Sep Oct Nov Dec Тemp. | 29 32 41 54 65 74 78 76 68 57 45 33 a) Use the graphing calculator to find an approximate equation of f(x) in the form y = a sin(k(x-b)) + c. Round a, b, k, and c to four decimal places. b) Using the model from a), what months will the temperature exceed 60°F?

Use the graphing utility to plot the graphs of y = cos (x) and y = 2x. (Enter multiple functions of x as a comma-separated list.) y = y 3. 2- -4 -3 -2 -1 4 3. 2- 4) 1.

Please answer ab

Sketch the graph of the function. y = 8 cos x/4
