The exam will cover the topics of Circles, Parabolas and Lines

Remember that the circle is defined by its CENTER and RADIUS

Remember that the important characteristics of a Parabola are: VERTEX, LINE OF SYMMETRY, X-Intercepts (“Roots”) and Y-Intercept

The Parabola has the two forms

General Form: $latex Ax^{2}+Bx+C=0$

Standard Form $latex A(x-h)^{2}+k=0$

The x-coordinate of the vertex is $latex \frac{-B}{2A}$

To get the y-coordinate of the vertex, put the x-value into $latex Ax^{2}+Bx+C$

and evaluate it.

The circle has the two forms

General Form: $latex Ax^{2}+Ay^{2}+Cx+Dy+C=0$

Standard Form $latex (x-h)^{2}+(y-k)^{2}=r^{2}$

The Center is at the point (h,k) and the radius = r.
