Here is the graph of the function $y = 2 \cos(x + 30^\circ)$. As you can see, the cosine curve has an amplitude of 2, and there is a phase shift of 30° to the left due to the "+30" inside the cosine function.

If you would like further details or explanations about the graph, feel free to ask!

Here are five related questions you might find interesting:

1. How does the phase shift in a cosine function affect its graph?
2. What is the general form of a cosine function, and how do different parameters like amplitude, period, and phase shift affect it?
3. How do you graph a cosine function from its equation step by step?
4. How does the period of a cosine function change when its coefficient is altered?
5. What is the relationship between radians and degrees on the x-axis of a trigonometric graph?

Tip: When graphing trigonometric functions, always start by identifying the amplitude, phase shift, and period to sketch the general shape before fine-tuning the details.
