Concept explainers
To find: Vertices and Foci of given conic.
Answer to Problem 3CT
Conic is Hyperbola.
Foci of Hyperbola are
Vertices of Hyperbola are
Explanation of Solution
Given information:
Graph of given Conic is
Here red line represents the given conic
So, from the graph we can say that given conic is Hyperbola.
If Hyperbola in the form
Then
Centre of Hyperbola is
Coordinates of Vertices of Hyperbola are
Coordinates of Foci of Ellipse are
Where
Comparing with general equation
We get
Therefore
Therefore
Foci of Hyperbola =
Foci of Hyperbola are
Vertices of Hyperbola =
Vertices of Hyperbola are
