Parabolas, circles, introduction to ellipses.

1. Parabolas ...
and circles and ellipses too!
12.1 Parabolas

2. And again: Sketch the graph, identify the vertex, focus, equation of the
axis of symmetry and the equation of the directrix.

4. the appropriate coordinate of the

5. the appropriate coordinate of the

6. Sketch the parabola defined by each equation, showing the coordinates of the
focus and the equation of the directrix. Also write the equation of the axis of
symmetry and the coordinates of the vertex.

7. Now, let's explore how we move from the standard form to the general
form and back again ...

8. The Circle
standard form for the
equation of a circle

9. Which equations represent circles? Find the radius, and the coordinates of the
centre of each circle.
