Football Review!

1. Football Review! Rules: 2 teams. Each team picks a quarterback and kicker. ONLY the quarterback may get out of his/her seat. Each person must do every single problem. When you have the ball and your captain says your team is ready (i.e. everyone on your team has the correct answer), I will choose which paper to look at for the answer. If you get it right, you get to attempt a field goal. If you don’t get it right you “fumble” and the other team gets to guess. The team with the most points at the end gets candy!!!

2. x y Number 1 Write an ordered pair for the point on the graph. Name the quadrant in which the point is located.

3. x y Number 2 Write an ordered pair for the point on the graph. Name the quadrant in which the point is located.

4. Number 3 • Plot each point on your own paper. • A (0,4) • B (-3,-1)

5. Number 4 • Express the following relation as a graph. Then determine the domain and range.

6. Number 5 Express the following relation as a mapping. Then determine the domain and range.

7. Number 6 -2 3 4 2 3 8 10 Express the relation shown in the mapping as a set of ordered pairs. Then state the inverse.

8. Number 7 Is (-1,2) a solution for x = 3y – 7?

9. Number 8 Is (-2,1) a solution for 2y + 4x = 8?

10. Number 9 Solve for y: 2x + y = 4

11. Number 10 Solve for y: 8x + 4y = 24

12. Number 11 Solve for y: 6x – 2y = 8

13. Number 12 • Solve y = -4x + 6 if the domain is {0,2,4} • You do not have to graph!

14. Number 13 Solve 2x + 2y = 14 if the domain is {-3,-1,0,1}. You do not have to graph.

15. Number 14 Solve y = 3x and graph for {-2,0,1,2}

16. Number 15 • Determine if this is a linear equation. If it is, rewrite it in standard form. 3x = 2y

17. Number 16 • Determine if this is a linear equation. If it is, rewrite it in standard form. 2x – 3 = y2

18. Number 17 • Determine if this is a linear equation. If it is, rewrite it in standard form. x = 12

19. Number 18 • Determine if this is a linear equation. If it is, rewrite it in standard form.

20. Number 19 Graph y = x - 1

21. Number 20 Graph

22. Number 21 Is the following relation a function and/or linear equation? (Could be 1, could be none, could be both!)

23. Number 22 Is the following relation a function and/or linear equation? (Could be 1, could be none, could be both!)

24. Number 23 Given f(x) = 3x + 7, find f(-2)

25. Number 24 Given f(x) = 3x + 7, find f(k+2)

26. Number 25 Given f(x) = 3x + 7, find 3[f(-4)].

27. Number 26 Given g(x) = x2 – 2x, find g(-3)

28. Number 27 Given g(x) = x2 – 2x, find g(4) +1

29. Number 28 Given g(x) = x2 – 2x, find -2[g(-1)]

30. Number 29 If g(x) = 11 – x and h(x) = -1/2 x + 4, find h(2) – g(-2)
