Which type of conic section is described by the following equation?
1 answer:
Answer:
C. Hyperbola opening up and down
Step-by-step explanation:
A graph tells the tale.
___
The term with the positive coefficient identifies the axis along which the hyperbola opens. Here, that is the y-axis, so the figure opens up and down.
The minus sign between the squared terms indicates it is a hyperbola, rather than a closed curve (ellipse or circle). The fact that both terms are squared indicates it is <em>not</em> a parabola.
