Solution 13306: Moving a Parabola Left or Right of the Y-Axis on TI-83 Family, TI-84 Plus Family, Or TI-Nspire™ Handheld in TI-84 Plus Mode.
How do I move a parabola left or right of the y-axis on a TI-83 Plus family or TI-84 Plus family graphing calculator?
Moving a parabola left or right of the y-axis cannot be done on the TI-83 Plus family and TI-84 Plus family calculators natively.
However, the Conic Graphing App allows parabolas and other conics to be moved left and right of the y-axis.
For further information please refer to the Conic Graphing App guidebook.
