Problem 139 of 7
Write a sinusoidal equation from graph features max 3, min -5, period 10, crosses midline at x=3 going down.
Using a hint is okay. It just tells the trainer to give you a little more review.

Identify amplitude, period, midline, phase, and sine/cosine choice.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Compute amplitude from half the max-min distance.
2. Compute midline as the average of max and min.
3. Find B from period 2pi/|B|.
4. Choose sine or cosine and set phase from an anchor.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
