Question

graph -3x^2+12y^2=849 what are the domain and range?

Answer 1

\[\frac{ 12y^2 }{ 849 }-\frac{ 3x^2 }{ 849 }=1\]
\[\frac{ y^2 }{ \frac{ 849 }{12 } }-\frac{ x^2 }{\frac{ 849 }{3 } }=1\]
\[\frac{ y^2 }{\frac{ 283 }{4 } }-\frac{ x^2 }{ 283 }=1\]
it is of the type \[\frac{ y ^{2} }{a^2 }-\frac{ x^2 }{ b^2 }=1\]
which is a hyperbola with axis on y-axis.

Answer 2

those are my choices.
