Unit 10 Review

KEY

Assignment for 1/4 (corrected + additions)

Okay, just about all I got right was the page number….  The problems on that page will be the hardest and I recommend doing them last!

Change that book assignment given in class to:  p530 #14-16,32-35  (again these are the hardest questions to be saved for last)

BUT BEFORE you do it, do these first:

--> Page 34 #16-20 all

--> Additional question 1.  What is the equation of a circle, centered at (3, 1), with a radius of √7?

--> Additional question 2.  What is the equation of a circle, centered at the origin, with a diameter of 12?

--> Additional question 3.  What is the radius of a circle if its center is at (-2, 1) and the point (3, 5) lies on the circle?

Test on Thursday, October 6h

Here are the topics for Thursday's test:


1.Linear equations:  using point-slope form to find equations of lines given:  slope and a point, two    
       points, line to be parallel to, line to be perpendicular to

2. Transformations of functions (powers, roots, absolute values, greatest integer) : translated, dilated,
      reflected over x-axis   NO GRAPHING CALCULATOR ALLOWED!

3. Domains and ranges of functions

4. Piece-defined functions

5. Polynomial functions:  zeros, max/mins, end-behavior, finding all zeros exactly using long division
     and quadratic formula
