Chapter 10: Q. 11 (page 699)

In problems11-18, 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 the parabola isy2=-8x

Step by step solution

01

Step 1. Given Information

The focus is at (-2,0)and the directrix line isx=2

02

Step 2. Calculation

Since the directrix line is x=2which is parallel to the y-axis then the equation of parabola having focus at (-2,0)is

y2=-4.2.x

03

Step 3. Final answer

Equation of parabola isy2=-8x

04

Step 4. Graph
