Graph Builder is an LTI that allows users to create graphs based on equations. You can embed the graph in course content.
In your course, create a page. Click Edit on the page, then click the Apps icon (it looks like an electrical plug). Choose View All in the drop-down menu.
Choose Graph Builder from the list of apps and click Done.
In the box that appears, click the plus sign to add in an equation. When you have the graph the way you want it, click Insert This Graph. The graph will be embedded on your page. Students will be able to interact with the graph by changing the formula or adding formulas to the existing list of formulas.
