Quadratic Equations in Vertex Form
Answered
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(xh)^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?

This is defined in the CAS View  it will load a lot faster (and fix this problem) if you define it in the Algebra View instead :)
I originally had it in the algebra view, but moved it to CAS so that it would display my rational numbers correctly. e.g. CAS will show y=1/3(xh)^2+k whereas algebra view shows me y=0.33(xh)^2+k.
I also would like to avoid using FractionText(1/2) because it puts the negative sign in the numerator instead of out front.
Is there a solution or fix that would allow me to keep it in CAS View?
