Bundle Description

The Exponential and Logarithmic Functions Unit (Unit 10) includes notes, practice, reviews, assessment, and activities.

Documents are in PDF format. Editable versions of all forms of the mid-unit assessment and test are also included in DOCX (MS Word) format.

The Exponential and Logarithmic Functions Unit (Unit 10) includes:

Geometric Sequences (Lesson 1)

· Write explicit and recursive formulas from applied problems

· Switch between explicit and recursive form

Exponential Functions (Lesson 2)

· Recognize exponential growth and decay from graphs and equations

· Graph and examine attributes of y=2^x, y=10^x, and y=e^x

· Introduction to Euler’s number, e

Exponential Transformations (Lesson 3)

· Transform y=2^x, y=10^x, and y=e^x

· Describe transformation from equations

· Multiple representations

· Effects of parameter changes on asymptotes and domain and range

Logarithmic Functions (Lesson 4)

· Rewrite logarithmic equations as exponential equations and vice versa

· Evaluate logarithmic expressions without a calculator

· Evaluate logarithmic expressions with a calculator

· Change of base formula

· Graphing logarithmic functions (base 2, 10, and e only)

Logarithmic Transformations (Lesson 5)

· Transform y=log(base2)(x), y=log(x), and y=ln(x)

· Describe transformation from equations

· Multiple representations

· Effects of parameter changes on asymptotes and domain and range

Concept Check (Review) and Mid-Unit Assessment (Quiz or Test)

· Solving using inverse properties (taking the log of both sides)

· Solving by rewriting

· Solving by graphing

Exponential Applications (Lesson 8)

· Formulate exponential equations from applied situations

· Exponential growth y=a(1+r)^t

· Exponential decay y=a(1-r)^t

· Compound interest A=P(1+r/n)^(nt)

· Continuously compounded interest A=Pe^(rt)

· Use equations to solve problems (evaluate and solve)

Solving Logarithmic Equations (Lesson 9)

· Solving with equivalent bases

· Solving using inverse properties (taking the log of both sides)

· Solving by rewriting

· Solving by graphing

· Applied situations

Properties of Logarithms (Lesson 10)

· Product, quotient, and power properties

· Expand logarithmic expressions

· Condense logarithmic expressions

· Solve logarithmic equations requiring the use of log properties

Concept Check (Review) and Unit Test (Multiple Choice or Free Response)

A note from Allison at Math Beach Solutions about standards alignment: This resource was designed from the ground up to provide ready-made resources for Texas teachers to implement to facilitate their students’ mastery of the Algebra 2 TEKS (Texas Essential Knowledge and Skills TAC §111.40). A considerable effort has been made to ensure the TEKS are addressed thoroughly, but these resources will reflect my understanding of the TEKS. As always, continue to use your professional judgement and experience when lesson planning.
