10. 3.3 Function Notation

11. Vocabulary:

12. Vocabulary:
The notation f(x), called function notation, is another name for y.

13. Vocabulary:
The notation f(x), called function notation, is another name for y.
This notation is read as “the value of f at x” or “f of x”.

14. Vocabulary:
The notation f(x), called function notation, is another name for y.
This notation is read as “the value of f at x” or “f of x”.
The parentheses do not imply multiplication .

15. Vocabulary:
The notation f(x), called function notation, is another name for y.
This notation is read as “the value of f at x” or “f of x”.
The parentheses do not imply multiplication .
You can use letters other than f to name a function. The letters g, h, j, and k are often used to name functions.

17. You know that a linear function can be written in the form;

18. You know that a linear function can be written in the form;
y = mx + b

19. You know that a linear function can be written in the form;
y = mx + b
Standard Notation

20. You know that a linear function can be written in the form;
y = mx + b
Standard Notation
By naming a linear function f, you can also write the function using function notation;

21. You know that a linear function can be written in the form;
y = mx + b
Standard Notation
By naming a linear function f, you can also write the function using function notation;
f(x) = mx + b

22. You know that a linear function can be written in the form;
y = mx + b
Standard Notation
By naming a linear function f, you can also write the function using function notation;
f(x) = mx + b

33. f(7)-9

34. f(7)-9 = 3X

35. f(7)-9 = 3X + 4

36. f(7)-9 = 3X + 4 =
3(7)

37. f(7)-9 = 3X + 4 =
3(7) + 4

38. f(7)-9 = 3X + 4 =
3(7) + 4 -9

39. f(7)-9 = 3X + 4 =
3(7) + 4 -9 = 21

40. f(7)-9 = 3X + 4 =
3(7) + 4 -9 = 21 + 4

41. f(7)-9 = 3X + 4 =
3(7) + 4 -9 = 21 + 4 -9

42. f(7)-9 = 3X + 4 =
3(7) + 4 -9 = 21 + 4 -9 = 25

43. f(7)-9 = 3X + 4 =
3(7) + 4 -9 = 21 + 4 -9 = 25 -9

44. f(7)-9 = 3X + 4 =
