Problem 62 of 7
Graph cosine function y=-3cos(pi*x)+5 using amplitude, period, midline, and phase shift.
Using a hint is okay. It just tells the trainer to give you a little more review.

Full solution stays hidden until you ask for it.
1. Write the cosine function in transformed form A cos(B(x-C))+D.
2. Compute amplitude, period, midline, and phase shift.
3. Plot one cycle beginning at a cosine maximum or minimum after transformations.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
