Answer

To graph the function \( y = 5 \sen\left(\frac{1}{4} x - \frac{\pi}{2}\right) \), use the following steps: 1. **Identify Key Features:** - **Amplitude:** 5 - **Period:** \( 8\pi \) - **Phase Shift:** \( 2\pi \) to the right - **Vertical Shift:** 0 2. **Create a Table of Values:** - Select \( x \) values from 0 to \( 8\pi \). - Calculate corresponding \( y \) values using the function. 3. **Plot the Points:** - Mark the points from the table on a coordinate plane. - Connect the points with a smooth sine wave curve. 4. **Key Points:** - Maximum at \( x = 4\pi \), \( y = 5 \) - Minimum at \( x = 0 \) and \( x = 8\pi \), \( y = -5 \) - Crosses the x-axis at \( x = 2\pi \) and \( x = 6\pi \) **Simplified Graph Description:** The graph is a sine wave with an amplitude of 5, a period of \( 8\pi \), and a phase shift of \( 2\pi \) to the right. It reaches a maximum of 5 at \( x = 4\pi \), a minimum of -5 at \( x = 0 \) and \( x = 8\pi \), and crosses the x-axis at \( x = 2\pi \) and \( x = 6\pi \).

Beyond the Answer

Para graficar la función \( y=5 \operatorname{sen}\left(\frac{1}{4} x-\frac{\pi}{2}\right) \), primero crearemos una tabla de valores. Tomemos algunos valores de \( x \) y calculamos los correspondientes valores de \( y \). | \( x \) | \( y \) | |----------|----------------------------| | -8 | -5 | | -4 | 0 | | 0 | 5 | | 4 | 0 | | 8 | -5 | | 12 | 0 | | 16 | 5 | Con la tabla de valores, podemos graficar los puntos en el plano cartesiano, notando que la función tiene un rango entre -5 y 5. La forma de onda de la gráfica será sinusoidal, reflejando la naturaleza periódica de la función seno, con un período más largo debido al coeficiente \( \frac{1}{4} \) frente a \( x \). ¡Diviértete creando la gráfica y observando cómo se desplaza esta onda!
