Lesson 5.2 (PART 2) FUNCTION NOTATION.

Functions Domain and range The domain of a function f(x) is the set of all possible x values. (the input values) The range of a function f(x) is the set.

Bellwork: Graph each line: 1. 3x – y = 6 2. Y = -1/2 x + 3 Y = -2

Warm-Up. Key Terms Relation – any set in which an input has an output Function – a relation such that every single input has exactly one output Input.

3.7.  Equations that represent functions are often written in function notation.  f(x) is used in place of y in function notation.  y = mx + b becomes.

Function Notation

Function form of an equation Function Notation is a way to name a function. It is pronounced “f of x” f(x) is a fancy way of writing “y” in an equation.

Evaluating Functions

Tell me what you get when x is -2. 1. Evaluating a function Tell me what you get when x is -2. f(x) = 2x + 3 when x = -2 f(-2) = 2(-2) + 3 f(-2) = - 4 + 3 f(-2) = - 1

Tell me what you get when x is 3. 2. Evaluating a function Tell me what you get when x is 3. f(x) = 32(2)x when x = 3 f(3) = 32(2)3 f(3) = 256

Tell me what you get when x is -3. 3. Evaluating a function Tell me what you get when x is -3. f(x) = x2 – 2x + 3 find f(-3) f(-3) = (-3)2 – 2(-3) + 3 f(-3) = 9 + 6 + 3 f(-3) = 18
