Answer 4

thats not a parabola, its a hyperbola ... if memory serves

Answer 5

y = 1/x is a hyperbola

Answer 6

well it says a parabola

Answer 7

It probably is a hyperbola the wording just wrong

Answer 8

it is clearly a hyperbola since it dos not even conform to the definition of a parabola

Answer 9

transverse, which axis is that?

Answer 10

yea I wolfram it too

Answer 11

insn't on the x axis?

Answer 12

transverse, the axis that the object crosses ... it should currently be along the y= -x line

Answer 13

yea that too

Answer 14

so that is a 30 degree angle?

Answer 15

Ima jsut go with 30 degrees since you leave

Answer 16

i moderate the site, i have to leave at times ..

Answer 17

y = 1/x and y= 6/x are the same 'axial' representations of the hyperbola

what degree is y = -x from the x axis?
