3.3 Function Notation
Vocabulary:
Vocabulary: The notation f(x), called function notation, is another name for y.
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”.
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 .
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.
You know that a linear function can be written in the form;
You know that a linear function can be written in the form; y = mx + b
You know that a linear function can be written in the form; y = mx + b Standard Notation
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;

8:05 f(2) =
8:05 f(2) = 3X + 4
f(2) = 3X + 4 = 3(2)
f(2) = 3X + 4 = 3(2) + 4
f(2) = 3X + 4 = 3(2) + 4 = 6
f(2) = 3X + 4 = 3(2) + 4 = 6 + 4
f(2) = 3X + 4 = 3(2) + 4 = 6 + 4 f(2) = 10
8:08 You Do f(4)
8:11
f(7)-9
f(7)-9 = 3X
f(7)-9 = 3X + 4
f(7)-9 = 3X + 4 = 3(7)
f(7)-9 = 3X + 4 = 3(7) + 4
f(7)-9 = 3X + 4 = 3(7) + 4 -9
f(7)-9 = 3X + 4 = 3(7) + 4 -9 = 21
f(7)-9 = 3X + 4 = 3(7) + 4 -9 = 21 + 4
f(7)-9 = 3X + 4 = 3(7) + 4 -9 = 21 + 4 -9
f(7)-9 = 3X + 4 = 3(7) + 4 -9 = 21 + 4 -9 = 25
f(7)-9 = 3X + 4 = 3(7) + 4 -9 = 21 + 4 -9 = 25 -9
f(7)-9 = 3X + 4 = 3(7) + 4 -9 = 21 + 4 -9 = 25 -9 f(7)-9 = 16
8:14 You Do f(4) -6
8:17
f(h+9) =
f(h+9) = 3X
f(h+9) = 3X + 4
f(h+9) = 3X + 4 = 3(h+9)
f(h+9) = 3X + 4 = 3(h+9) + 4
f(h+9) = 3X + 4 = 3(h+9) + 4 = 3h + 27
f(h+9) = 3X + 4 = 3(h+9) + 4 = 3h + 27 + 4
f(h+9) = 3X + 4 = 3(h+9) + 4 = 3h + 27 + 4 f(h+9) = 3h + 31
8:20 You Do f(h+12)
