For Exercises 21 to 26, use the grid and your compass (as needed) to locate several points on the parabola having the given focus F and directrix d . Then sketch the parabola that is characterized by these points.

Chapter 7.1, Problem 21E, For Exercises 21 to 26, use the grid and your compass as needed to locate several points on the

To determine

To sketch:

The parabola using the below given grid with directrix and focus.

Elementary Geometry for College Students, Chapter 7.1, Problem 21E

Explanation

Definition:

A parabola is the locus of points that are equidistant from a fixed line and a fixed point not on that line.

The fixed point is known as focus of the parabola and the fixed line is known as directrix of the parabola.

Procedure:

1. Draw the given directrix d and focus F and locate a point D1.

2. Locate a point P1 which is the mid-point of FD1. The point P1 will be the vertex.

3. Locate the points P1, P2, P3, P4, and P5 such that D1P1=P1F, D2
