When appropriate, use Image size to create a square document. The measurements are in centimeters. While 16.5 cm will make it fill the entire page horizontally, it will also take a lot of space vertically. You may want something smaller like 11.7 or 8.1, which will allow two side-by-side images.
Use Bitmap to clipboard to capture the image so you can paste it into Google Docs. The regular copy to clipboard doesn't work.
Be sure to Save your graphic so that you can re-edit later if you need to do so.

Use implicit to graph an implicit equation. Sometimes, implicit graphs have a problem displaying if you change the zoom or arrow around to change the viewing. A workaround is to edit the graph in the inventory and then change the color.
The inventory has a derive button that will graph the derivative of the selected function. The graph button will show or hide a graph, so a good way to make matching graphs is to sketch the function and derivative to make sure both are going to fit reasonably well on in the viewing window and then show one while hiding the other when you copy and paste the graph.

Use Grid to control the visibility of the grid, axes, tick marks, and labels. I recommend using a rectangular grid with dotted lines in all four quadrants. Check the scale box to show the numeric labels on the axes.
Use View to control the domain and range of the image.

Use Text to add labels to the graph. Use the right mouse button to add or edit text and the left mouse button to drag it and change its position.

Use Measurement > Integrate to determine the areas. After setting it up, click on Definite to obtain the estimates.
