Test Preparations

Be able to find the

  -  zeros

  -  y-intercept

  -  axis of symmetry

  -  vertex 

of a quadratic function that is in standard form or factored form.

Ex.  3x^2 – 9x – 30

Be able to write an equation (factored and standard form) from a graph or scatter plot (ie. plot data.)

Solve quadratic equations by factoring.

  - find x, (usually two answers ;) )

Solve word problems:

- Profit type questions

- Population type questions

- Projectile type questions (anything that flies through the air.)

For word problems:

-  Look for vertex to find maximum or minimum.

-  Substitute and solve to find a specific variable.

   (what time, how high, what speed… find x or y.)
