Solution
-
Abre Excel y copia los datos proporcionados en dos columnas, una para "x" y otra para "y".
-
Selecciona los datos y ve a la pestaña "Insertar". Luego, selecciona "Gráfico de dispersión" para crear un gráfico de dispersión con los datos.
-
Haz clic derecho en uno de los puntos de datos en el gráfico y selecciona "Agregar línea de tendencia".
-
En el panel de "Agregar línea de tendencia", selecciona "Polinómica" y establece el "Orden" en 2 para crear una línea de tendencia cuadrática.
-
Asegúrate de marcar la opción "Mostrar ecuación en el gráfico" para que Excel muestre la ecuación de la línea de tendencia en el gráfico.
-
La ecuación de la línea de tendencia cuadrática aparecerá en el gráfico. Según los datos proporcionados, la ecuación debería ser similar a una de las opciones dadas.
-
Compara la ecuación mostrada en el gráfico con las opciones proporcionadas:
- 𝑦=3.3824𝑥+650.91
- 𝑦=421.56𝑥0.214
- 𝑦=−12.25𝑥2+200𝑥+99.25
- 𝑦=582.85𝑒0.0103𝑥
-
La ecuación que mejor se ajusta a los datos es: 𝑦=−12.25𝑥2+200𝑥+99.25.
