Lesson 3 6 b Graphing Identifying Key Features

Lesson 3. 6 b Graphing & Identifying Key Features of Exponential Functions Concept: Characteristics of Exponential Functions Lesson EQ: How do you graph, interpret, and apply the key features of an exponential function? (Standard F. IF. 4, 5, 7) Vocabulary: Domain, Range, & End Behavior

Recall • Exponential Functions

Guided Practice: Example 1, continued Complete the table of values to create a graph of the function. x f(x) – 2 – 1 0 1 2 3 3. 4. 2: Graphing Exponential Functions

Domain •

Range •

End Behavior •

Guided Practice: Example 2, continued Complete the table of values to create a graph of the function. x f(x) – 2 – 1 0 1 2 7 3. 4. 2: Graphing Exponential Functions

Recall • Not a reflection • Decay • Horizontal Asymptote: y = 0 • y-intercept: (0, 1) •

Guided Practice: Example 3, continued Complete the table of values to create a graph of the function. x f(x) – 2 – 1 0 1 2 9 3. 4. 2: Graphing Exponential Functions

Recall • Not a reflection • Growth • Horizontal Asymptote: y = 1 • y-intercept: (0, 2)

Guided Practice: Example 4, continued Complete the table of values to create a graph of the function. x f(x) – 2 – 1 0 1 2 11 3. 4. 2: Graphing Exponential Functions

Recall • Reflection • Decay • Horizontal Asymptote: y = 3 • y-intercept: (0, 2)

Summarizing Strategy: Example for Absent friend Your absent friend needs you to show them an example of what they missed. Choose 3 of the following 5 features to identify for this exponential function: f(x) = 3 x – 2 • Asymptote • y-intercept • Domain • Range • End Behavior
