Which conic section does the equation attached describe? A. Circle B. Ellipse C. Parabola D. Hyperbola **my answer: B. ellipse is that right? =)
\[\huge \left(\frac{x}{a}\right)^2+\left(\frac{y}{b}\right)^2=1\] See the addition sign between them? Hmm I don't think that quite matches what we're looking for.
Hyperbola has form \[\frac{(x-h)^2}{a}+\frac{(y-k)^2}{b}=1\]
ohhh okay so then I'm not too sure :(
That is the standard form of an ellipse* the one i posted before. Sorry my broswer really screwy :c grr
no mat :O don't confuse heart. Click the picture for the function, don't look at what I posted.
ohhh okay hahaa :P wait so I'm confused... what is this then?? :/
It's a hyperbola... as anhuya said :O
Oh she posted the wrong sign between them I think.. ugh sec lemme look it up XD
ohh i see :) it follows that format... :)
ok :) so what is it then??? :/
Sorry everyone, mistype Hyperbola form is \[\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1\]
I find these a little confusing because of all the extra numbers they throw at you. The -1 in x -1 just represents a horizontal shift to the right 1 unit. It doesn't affect the SHAPE of the graph at all. So I would recommend ignoring data like that. It might help you to see what's going on. The function essentially looks something like this,\[\huge \left(\frac{x}{a}\right)^2-\left(\frac{y}{b}\right)^2=1\]
okay, so i need to find the one that follows that format?
It might appear in your book as anhuya posted it.
okay, so this is a hyperbola? :/
like @anhhuyalex said?
okay!!! thank youu :)
its hyperbola i din't look ur post
