anyone know how to put a f(y) function into a ti 84?

[opaque jay]

im trying to graph x=1-y^2 on my ti84

[fringe hill]

What's ti84

[low trout]

Which TI-84 model is it? Is it a TI-84 Plus C Silver Edition, TI-84 Plus CE, TI-84 Plus Silver Edition, TI-84 Plus. There are many models so which is it?

plus ce

i was able to do it in parametric mode, is there any other way?

Are you familiar with conics? Go to apps > 4:Conics > 4: Parabola
There are two options
Option 1 is for horizontal parabolas (left, right)
Option 2 is for vertical parabolas (up,down)
This parabola is a horizontal so press 1 which gives you the equation of a horizontal parabola.
Enter values h,k and p.

h is the first point of the vertex and k is the second point of the vertex. P is the distance from vertex to the focus.

im wanting to do this for any f(y) in general not just horizontal parabolas

but yeah im familiar with that

The second option is for vertical parabolas and when you press 4 conics you see that there are other options such as circles, ellipses, and hyperbolas.

This is a horizontal parabola so when you press 1 horizontal enter h=1, k=0, p= 1/4 and you get the graph.
