Solution
The image you uploaded contains a graph of a trigonometric function, and the problem asks to determine the parameters , , , and for the general form of the function:
Let's break down the graph to identify these parameters.
1. Amplitude :
- The amplitude is the distance from the midline (average value) to the maximum or minimum value of the function.
- Looking at the graph, the maximum value appears to be and the minimum value is . Thus, the amplitude is:
2. Vertical Shift :
- The vertical shift is the average value or the midline of the function.
- This can be found by taking the average of the maximum and minimum values:
3. Angular Frequency :
- The angular frequency is related to the period of the function, where .
- From the graph, the period is the distance between two successive points where the function starts repeating. It appears that the period is , so:
4. Phase Shift :
- The phase shift can be determined by observing where the function reaches a significant point (like the maximum or the zero crossing).
- If we take the standard sine function, . In the graph, the function appears to cross the midline from below at , so the phase shift is .
Given this analysis, the function can be written as:
Would you like further details or have any questions about this problem? Here are five related questions you could explore:
- How would the function change if the amplitude were doubled?
- What happens to the graph if the vertical shift is increased by 2?
- How does altering the period affect the angular frequency ?
- Can you describe the impact of a phase shift on the sine function?
- How would the graph look if a cosine function were used instead of a sine function?
Tip: When analyzing trigonometric functions, always start by identifying the amplitude and period, as they directly affect the shape and frequency of the graph.
