    ok, my question is " what does graphing technology?" I always graph by hand, don't know how to use "technology"

    so, you can solve it by yourself? no need to stay ? right? actually, I am a super lazy guy. If you don't need help anymore, I glad to hear that. hehehe

    shoot.what is your equation? for hyperbola?

    foci at (0, ±10) and vertices at (0, ±8) Make this into an equation

    remember that foci (0,+-c) and vertices (0,+-a) and c^2 = a^2 + b^2( use this form to find out b) and put everything into the standard form of hyperbola \[\frac{y^2}{a^2}-\frac{x^2}{b^2}=1\]

    and draw the asymptotes by \[y= (+-)\frac{a}{b}*x\]

    remember that if your foci is (0,+- c) your hyperbola has the shape like|dw:1369325453179:dw|

    so b^2 = 100 - 64 = 36 so ?

    100=64+b^2 36=b^2 6=b

    \[\frac{y^2}{64}-\frac{x^2}{36}=1\] your equation form is a^2 and b^2 , you need a, b when you have to figure out the asymptotes only. to get the form of hyperbola, no need to get that far

    if you have to sketch the graph, you have to sketch the asymptotes, too. but it's quite easy when you have a, b, just draw the lines out.
