2. THIS….. IS… JEOPARDY!

3. Is it a function?

4. Yes! (Each x has only one y)

5. Is it a function?

6. No (The 3 in the domain has two different range values)

7. Is it a function?

8. No (It does not pass the vertical line test)

9. Is it a function?

10. Yes (It passes the vertical line test)

11. Is it a function?

12. Yes (Passes v- line test)

13. Simplify

33. These are the two tests used to determine whether something is a function

34. Mapping Diagram Vertical Line Test

35. If you see this in the vertical line test, you know the relation is NOT a function

36. A vertical line hits 2 or more points on the graph

37. Give the domain and range of the relation

39. This is what you look for in a mapping diagram to determine whether or not something is a function.

40. *Arrows coming from the DOMAIN: 2 arrows from one number Not a function 1 arrow from each number Function

41. Give the definition of a function.

42. A relation where each element in the domain is paired with exactly one element in the range.

43. If you’re told to find f(5), what do you do with the number 5?

44. Replace all the x’s in the function with 5

45. Given find f(-4)

46. -8

47. Given find f(2c)

49. Given Find p(3)

50. 25

51. Given Find 3p(2)

52. 51
