Problem 72 of 7
Write a cosine model from graph features maximum 7, minimum -3, period 10, maximum at x=0.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
use amplitude, period, midline, and phase shift.
Hidden until you reveal it.
Use amplitude, period, midline, and phase shift for graphs starting at max or min.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Find amplitude and midline from max/min.
2. Compute B=2pi/period.
3. Use maximum or minimum location for cosine phase and sign.
4. Write the model.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Sine/cosine phase choices that do not match the starting condition.
