It is possible to add an image to a Desmos graph.
Note the option to add an image…
Remembering the beautiful dance moves poster I thought I’d see how accurate it is!
The modulus function looks pretty good – as does the circle (though it really should not be labelled just x2+y2)
Anyway – upload an image – save your page and challenge your students to fit a graph!
Remembering a holiday in Barcelona – I thought I would add the graph of cosh x to this photo.. Select the image to see the Desmos graph page.
Note the use of the drop down menu in each section.
