Answer

To graph the function \( f(x) = 4 \csc \left( \frac{x}{4} - \frac{\pi}{2} \right) + 2 \), follow these steps: 1. **Create a Table of Values**: - \( x = 0 \): \( f(0) = -2 \) - \( x = 2\pi \): \( f(2\pi) = 6 \) - \( x = 4\pi \): \( f(4\pi) = -2 \) - \( x = 6\pi \): \( f(6\pi) = 6 \) - \( x = 8\pi \): \( f(8\pi) = -2 \) 2. **Plot the Points** on a graph with the x-axis ranging from \( 0 \) to \( 8\pi \). 3. **Draw the Graph**: - The function has vertical asymptotes at \( x = 4n\pi + 2\pi \) for integer values of \( n \). - It reaches its maximum value of 6 and minimum value of -2. - The graph will have a period of \( 8\pi \). This will give you a clear visual representation of the function's behavior over one period.

Solution

Function by following steps: - step0: Determine the period: \(f\left(x\right)=-4\sec\left(\frac{x}{4}\right)+2\) - step1: Calculate: \(f\left(x\right)=-4\sec\left(\frac{1}{4}x\right)+2\) - step2: The period of the function is \(\frac{2\pi }{\left|\frac{1}{4}\right|}:\) \(\frac{2\pi }{\left|\frac{1}{4}\right|}\) - step3: Calculate: \(\frac{2\pi }{\frac{1}{4}}\) - step4: Divide the terms: \(8\pi \) Analyze the y intercept of the function \( f(x)=4 \csc \left(\frac{x}{4}-\frac{\pi}{2}\right)+2 \) Function by following steps: - step0: Find the y-intercept: \(f\left(x\right)=-4\sec\left(\frac{x}{4}\right)+2\) - step1: Set \(x\)=0\(:\) \(f\left(0\right)=-4\sec\left(\frac{0}{4}\right)+2\) - step2: Simplify: \(f\left(0\right)=-2\) Analyze the x intercept of the function \( f(x)=4 \csc \left(\frac{x}{4}-\frac{\pi}{2}\right)+2 \) Function by following steps: - step0: Find the \(x\)-intercept/zero: \(f\left(x\right)=-4\sec\left(\frac{x}{4}\right)+2\) - step1: Set \(f\left(x\right)\)=0\(:\) \(0=-4\sec\left(\frac{x}{4}\right)+2\) - step2: Swap the sides: \(-4\sec\left(\frac{x}{4}\right)+2=0\) - step3: Move the constant to the right side: \(-4\sec\left(\frac{x}{4}\right)=0-2\) - step4: Remove 0: \(-4\sec\left(\frac{x}{4}\right)=-2\) - step5: Change the signs: \(4\sec\left(\frac{x}{4}\right)=2\) - step6: Divide both sides: \(\frac{4\sec\left(\frac{x}{4}\right)}{4}=\frac{2}{4}\) - step7: Divide the numbers: \(\sec\left(\frac{x}{4}\right)=\frac{1}{2}\) - step8: Rearrange the terms: \(x \notin \mathbb{R}\) - step9: There is no \(x\)-intercept\(:\) \(\textrm{No x-intercept}\) It seems that I am unable to generate a graph at this moment. However, I can guide you on how to plot the function using graphing software or tools like Desmos or GeoGebra. ### Steps to Plot the Function 1. **Open a Graphing Tool**: Use a graphing calculator or an online graphing tool like Desmos. 2. **Input the Function**: Enter the function \( f(x) = 4 \csc \left( \frac{x}{4} - \frac{\pi}{2} \right) + 2 \). 3. **Set the Range**: Adjust the x-axis to cover the interval from \( 0 \) to \( 8\pi \) (approximately \( 25.13 \)). 4. **Observe the Graph**: Look for the vertical asymptotes where the function is undefined, and note the behavior at the y-intercepts and critical points. ### Summary of Key Points - **Domain**: Excludes points where \( x = 4n\pi + 2\pi \). - **Range**: \( (-\infty, -2] \cup [6, \infty) \). - **Y-Intercept**: \( f(0) = -2 \). - **X-Intercept**: None. - **Periodicity**: The function has a period of \( 8\pi \).

To graph the function \( f(x) = 4 \csc \left(\frac{x}{4} - \frac{\pi}{2}\right) + 2 \), let's first create a table of values: | \( x \) | \( f(x) \) | |-------------|---------------| | \( 0 \) | \( 4 \csc(-\frac{\pi}{2}) + 2 \) = Undefined | | \( 2 \) | \( 4 \csc(-\frac{\pi}{2} + \frac{1}{2}) + 2 \) = Undefined | | \( 4 \) | \( 4 \csc(0) + 2 \) = Undefined | | \( 6 \) | \( 4 \csc (\frac{3\pi}{4}) + 2 \) = \( 4(-\sqrt{2}) + 2 \approx -4.66 \) | | \( 8 \) | \( 4 \csc(\frac{\pi}{2}) + 2 \) = \( 4(1) + 2 = 6 \) | | \( 10 \) | \( 4 \csc (\frac{7\pi}{4}) + 2 \) = \( 4(\sqrt{2}) + 2 \approx 8.66 \) | | \( 12 \) | \( 4 \csc(3\pi/2) + 2 \) = Undefined | | \( 14 \) | \( 4 \csc (\frac{5\pi}{4}) + 2 \) = \( 4(-\sqrt{2}) + 2 \approx -4.66 \) | | \( 16 \) | \( 4 \csc(2\pi) + 2 \) = Undefined | Note: The values where \( f(x) \) is undefined correspond to points where \( \csc \) is undefined, specifically where \( \sin = 0 \). Next, let's summarize what the graph of this function would look like: 1. The function has vertical asymptotes where \( \sin\left(\frac{x}{4} - \frac{\pi}{2}\right) = 0 \), which occurs at points \( x = (n\pi + 2\pi) \) for \( n \) being an integer. 2. The function oscillates between values ranging from negative infinity to positive infinity, with a repeating pattern every varying interval determined by the period of the sine function. Now, you can use software like Desmos or a graphing calculator to plot the function based on this table. Note where the undefined points occur, as they'll result in vertical asymptotes in your graph!
