1. Problem Description
The problem asks to graph the function .
2. Solution Steps
The general form of a cosine function is , where:
is the amplitude.
The period is .
The phase shift is .
is the vertical shift.
In our case, . Comparing with the general form, we have:
The amplitude is .
The period is .
The phase shift is .
The vertical shift is .
The function is a cosine function shifted to the right by .
The standard cosine function starts at , reaches , , and ends at .
Since the phase shift is , we shift these points to the right by .
The key points of the graph are:
3. Final Answer
The graph of is a cosine curve with amplitude 1, period , and phase shift to the right. The key points for one period are , , , , and .
