  2. Worksheet KEY

  3. Trashball Jeopardy!

  4. RULES: Teams of max 4. Each team rotates on choosing what category to pick Every team has a certain time limit to solve each question Each team who gets it right will get the amount of points Each team who gets it right, will elect someone to shoot. Everyone must shoot. No daily doubles or final jeopardy.

  11. In the Intervals : 1 Point • QUESTION: • Write this in Interval Notation, • ANSWER:

  12. In the Intervals : 2 Points • QUESTION: • Solve in Interval Notation and graph on a number line, 2(x+ 1) < x – 2 • ANSWER:

  13. In the Intervals : 3 Points • QUESTION: • Solve and graph on a number line, 2 – 5x>3x– 14 • ANSWER:

  14. In the Intervals : 4 Points • QUESTION: • Solve and graph, x+ 3 > 6 or 3 – 2x> 9 • ANSWER:

  15. In the Intervals : 5 Points • QUESTION: • Solve and graph, • ANSWER: • All Real Numbers (–∞, ∞)

  16. Let's Translate : 1 Point • QUESTION: • Identify the new equation, if the parent function is a quadratic function and it moves 3 units up and 4 units to the left • ANSWER: • y = (x + 4)2 + 3

  17. Let's Translate : 2 Points • QUESTION: • Identify the equation using the picture below: • ANSWER: • y = |x + 5| – 3

  18. Let's Translate : 3 Points • QUESTION: • What is the domain and range of this function below? Then, describe the shift from parent function. • ANSWER: • ; Left 3, • Reflected • Domain: [–3, ∞) • Range: (–∞, 0]

  19. Let's Translate : 4 Points • QUESTION: • Identify the parent function using these points: {(–2, –7), (–1, 0), (0, 1), (1, 2), and (2, 9)} • ANSWER: • Cubic

  20. Let's Translate : 5 Points • QUESTION: • Given these points: {(–2, –7), (–1, 0), (0, 1), (1, 2), and (2, 3)} and instead of (–2, –7) and (–1, 0), we replace it with (–2, 3) and (–1, 2), what is the new parent function? • ANSWER: • Absolute Value

  21. Mother Functions : 1 Point • QUESTION: • Identify whether it is a function. If it is a function, identify the domain and range in Interval Notation • ANSWER: • It is a function, one domain has one range.

  22. Mother Functions : 2 Points • QUESTION: • Identify whether it is a function. If it is a function, identify the domain and range in Interval Notation. • ANSWER: • Yes, it is a function • D: (–∞, ∞), R: (–∞, 0] U [–2] U • (2, ∞)

  23. Mother Functions : 3 Points • QUESTION: • What is the parent function equation for this graph? • ANSWER: • y = x3

  24. Mother Functions : 4 Points • QUESTION: • Solve for f (0), f (1) and f (–2) for f (x) = 3x3 + 1 • ANSWER: • f (0) = 1, f (1) = 4 and f (–2) = –23

  25. Mother Functions : 5 Points • QUESTION: • What is the only parent function whose domain and range is all real numbers but zero? Why? • ANSWER: • Rational/Reciprocal function because zero causes the equation to be undefined.

  26. Not Equal : 1 Point • QUESTION: • Solve as an inequality, 2(y + 3) – 8 < 4y + 2 • ANSWER: • y> –2

  27. Not Equal : 2 Points • QUESTION: • Solve as an inequality, 9x + 4 < 12x – 11 • ANSWER: • x > 5

  28. Not Equal : 3 Points • QUESTION: • Solve OR as an inequality • ANSWER: • x< –4 or x > 5
