I’ve got a clip that graphs a parabola by adjusting the x intercepts on a graph and the vertex position.
I need to be able to extend the parabola lines past the x, but can’t figure it out…I think I need to plug in a large (or small depending on the vertex) y value and then find an x value and then draw lines from the end of the parabola to the new point, but I’ve tried that and it looks like two lines shooting off the curved parabola…
Anyone??
I’ve tried numerous different parabola options using equations, but they aren’t build so you adjust the x intercepts with the sliders…
