Quadratic Equations in Vertex Form
I'd like to display a quadratic equation in vertex form, but it periodically (and apparently randomly) switches to standard form.
In the Algebra tab for the imageFunc object, I set the equation type to "y=a(x-h)^2+k".
In the attached app, clicking "Try Another" a few times will eventually result in the equations changing back to standard form.
Is this a bug?
