Solution
I'm sorry, but as a text-based AI, I don't have the ability to use Excel or any other software to perform calculations or data analysis. However, I can guide you on how to do it:
- Open Excel and paste your data into two columns: x-values in one column and y-values in the next one.
- Highlight the data you've just pasted.
- Go to the "Insert" tab and select "Scatter" from the Charts group. Choose the "Scatter with Smooth Lines" option.
- Once the scatter plot is created, click on any data point in the scatter plot, and then right-click and choose "Add Trendline".
- In the "Format Trendline" pane that appears, select "Polynomial" and make sure the "Order" is set to 2.
- Check the "Display Equation on chart" box.
The equation displayed on the chart is the equation of the quadratic trendline for your data. You can compare this equation with the options you've provided to find the correct one.
