# Question #a3b13

##### 1 Answer

#### Answer:

Please see the explanation.

#### Explanation:

Given:

Write in standard form,

The y coordinate, k, of the vertex and the focus is:

The x coordinate, h, of the vertex is the equation evaluated at y = k= -1:

The vertex is the point

Find the focal distance, f:

The x coordinate of the focus is the x coordinate of the vertex plus the focal distance and the y coordinate is the same.

The focus is

The directrix is a vertical line at the x coordinate of the vertex minus the focal distance:

For the x intercept evaluate the equation at

Evaluate the discriminant:

There are no real y intercepts.
