Note: Exercises preceded by an asterisk are of a more challenging nature.
For Exercises 23 to 28, use the grid and your compass (as needed) to locate several points on the parabola having the given focus F and directrix . Then sketch the parabola that is characterized by these points.
The parabola using the below given grid with directrix and focus.
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.
1. Draw the given directrix and focus and locate a point .
2. Locate a point which is the mid-point of . The point will be the vertex.
3. Locate the points , , and such that
