8:00 Date: Wednesday October 11, 2017 Algebra 1 - Agenda EQ: How can you use function notation to represent a function? HAS-IF.A.2 Objective: S.W.B.A.T; Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context by; Evaluating a function Interpreting function notation Solving for the independent variable Graphing a linear function in function notation Homework: P. 125# 12, P. 126 # 32, 37 & 38

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 Function Notation

24
8:05 f(2) =
25
8:05 f(2) = 3X + 4
26
f(2) = 3X + 4 = 3(2)
27
f(2) = 3X + 4 = 3(2) + 4
28
f(2) = 3X + 4 = 3(2) + 4 = 6
29
f(2) = 3X + 4 = 3(2) + 4 = 6 + 4
30
f(2) = 3X + 4 = 3(2) + 4 = 6 + 4 f(2) = 10
31
8:08 You Do f(4)
32
8:11
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 = 3(7) + 4 -9 = 21 + 4 -9 = 25 -9 f(7)-9 = 16
45
8:14 You Do f(4) -6
46
8:17
47
f(h+9) =
48
f(h+9) = 3X
49
f(h+9) = 3X + 4
50
f(h+9) = 3X + 4 = 3(h+9)
51
f(h+9) = 3X + 4 = 3(h+9) + 4
52
f(h+9) = 3X + 4 = 3(h+9) + 4 = 3h + 27
53
f(h+9) = 3X + 4 = 3(h+9) + 4 = 3h + 27 + 4
54
f(h+9) = 3X + 4 = 3(h+9) + 4 = 3h + 27 + 4 f(h+9) = 3h + 31
55
8:20 You Do f(h+12)
