Do not lose this assessment. Do all your math on your own paper. Do not write on this assessment.

1.  No or Yes: The following ordered-pairs can represent a function.
           Briefly explain your answer.
       (0,2)  (1,4)  (2,2)  (1,4)  (0,2)  (4,1)
2.  No or Yes: The following ordered-pairs can represent a function.
           Briefly explain your answer.
       (1,0)  (-1,0)  (2,0)  (-2,2)  (1,2)   (2,0)
3. Assume there is a function Q(t). Write  Q(-4) = 2  as an ordered-pair.
4. If the domain of Q(t) is all whole numbers, then  Q(3.14)  equals what?
5. Subtract and Simplify:  (-5x^2 - 3x - 7) - (-2x^2 - x - 4)
6. Multiply and Simplify:  (-2n - 1)(-3n - 5)
7. Solve for x:  -2(-3x + -1) - 2x = -8(x - 2)
