Chapter 10: Q. 11 (page 699)

In Problem 11-18, find an equation of the conic described, Graph the equation by hand.

Parabola; focus at -2,0; directrix the linex=2

Short Answer

Expert verified

The equation of parabola isy2=-8x

Step by step solution

01

Step 1. Given information

The focus of the parabola is at -2,0and the directrix of the line is

x=2

02

Step 2. Calculation

Since co-ordinate of focus is -2,0and directrix is x=2

Then the equation of the parabola is y2=-4.2.x

i.e.y2=-8x

03

Step 3. Calculation
