Question

The graph displays which of the following equations?

Answer 1

heres the attachment

Answer 2

you know it has to be
\[\frac{y^2}{a^2}-\frac{x^2}{b^2}=1\] because of the way it opens

Answer 3

since the vertices are at (0,3) and (0,-3) you know
\[3^2=9\] is in the denominator of the
\[y^2\] term

Answer 4

therefore A is your answer

Answer 5

its A. as @satellite said, its of that format, plus its vetices are (3.0) and (-3,0). so the part below y^2 will be be 3^2 that is 9. so A.
