The answer key below is WRONG on problem #31.  The answer should be d = 12.

Also as discussed in class, the answers to #18 were for a different problem.  The mapping should point to the 0,2,4,and 6, with two arrows ending at 2 and 4.  The set of ordered pairs should be:  {(2,4), (3, 2), (4, 0), (5, 2), (6, 4), (7, 6)}, the domain is 2, 3, 4, 5, 6, 7, the range is 0, 2, 4, 6, and it is a function.

What r and r^2 mean:   JUST R (correlation coefficient)
                                      LONG BUT INTERESTING ON R^2  (coefficient of determination)
Using DESMOS:     MOSTLY LINEAR EXAMPLES  and  QUADRATIC EXAMPLE

The link for the key is below.  Please be aware of a couple of things:
1)  In the last section, every problem that says "real" should be replaced with "rational."  Also:  2 imaginary solutions is equivalent to no solution
2)  On the real test tomorrow, there will be some irrational solutions in that last section.
3)  In the problems where you clear fractions, expect at least one problem where there will be two answers (solving a 2nd degree equation).

Assignment for Tournament Thursday, 2/18/2016

Remember, when it comes to "karate-chop" lines, a formula such as y = mx + b is NOT that useful.  Common sense and sketches of the situation should be used instead!!
