Topic: conics? (parabola & hyperbola)

how do you graph a parabola and a hyperbola?

ex. parabola: (y+5)^2= 8(x-8)

ex. hyperbola: (y-3)^2/4-(x+1)^2/p=1

Re: conics? (parabola & hyperbola)

To insert them as functions, you have to isolate y, e.g.

f(x) = sqrt(8(x-8))-5 and f(x) = -sqrt(8(x-8))-5

f(x) = 3+sqrt(4+4(x+1)^2/p) and f(x) 3-sqrt(4+4(x+1)^2/p)

Type them directly in the "relation" field.
