Work Step by Step

We are given the hyperbola: $-y^2+x^2=3$ Bring the equation to the standard form: $\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1$ $\dfrac{x^2}{3}-\dfrac{y^2}{3}=1$ The transverse axis is parallel to the $x$-axis. Determine $h,k,a,b,c$: $h=0$ $k=0$ $a^2=3\Rightarrow a=\sqrt 3$ $b^2=3\Rightarrow b=\sqrt 3$ $c^2=a^2+b^2$ $c^2=3+3$ $c^2=6$ $c=\sqrt 6$ Determine the coordinates of the vertices: $(h-a,k)=(0-\sqrt 3,0)=(-\sqrt 3,0)$ $(h+a,k)=(0+\sqrt 3,0)=(\sqrt 3,0)$ Determine the coordinates of the co-vertices: $(h,k-b)=(0,0-\sqrt 3)=(0,-\sqrt 3)$ $(h,k+b)=(0,0+\sqrt 3)=(0,\sqrt 3)$ Determine the coordinates of the foci: $(h-c,k)=(0-\sqrt 6,0)=(-\sqrt 6,0)$ $(h+c,k)=(0+\sqrt 6,0)=(\sqrt 6,0)$ Graph the hyperbola:
