Curve sketching questions (1 Viewer)

Hey all

How do I sketch the following curves , and include the domain and range in the answer?


1) 9x^2 + 9y^2 + 9x + 6y +1 = 0
2) y=-4^-x
3) y=1-2^-x
4) y= -3/x
5) xy=8

Thanks

So how would I sketch the circle? I figured out the others. Complete the square to bring it into (x-k)^2 + (y-a)^2 = r^2 ??

Just tried it again. Found the *root* of he problem .Turns out 9- (-9) isn't zero. :facepalm:

Thanks for confirming
