Using Desmos.com

April 15, 2015

grade 10s looked at desmos.com today to investigate parabolas in the form y=a(x-h)^2+k (note, the little ^2 is the oldschool way to show someing as squared)

  

We changed values of h and k to move the graph around, and we changed the a value to change the shape of the graph.

We took images of the water fountain and matched the water’s arch with a parabola. 

We looked for neat real world parabola pictures online and matched the images with parabolas. 

   

  

We cant stop seeing parabolas!
