Chapter-Specific Changes

Chapter 1: Prerequisites

Introduction

• In the last statement, ‘and trigonometry.’ was deleted.  “This understanding will serve as prerequisite knowledge throughout our study of algebra and trigonometry.”

Real Numbers

• First Try It under Formulas – added a more detailed solution.

Polynomials

• Deleted the Learning Objective – “Use FOIL to multiply binomials” since this topic falls underneath the Multiplying Polynomial objective.

Chapter 2: Equations and Inequalities

Linear Equations in One Variable

• Changed Learning Objectives: Solve equations in one variable algebraically.

Model and Applications

• Deleted “access online resource video section”

Linear Inequalities and Absolute Value Inequalities

• Changed objectives:
  • Use interval notation. Write solutions using interval notation.
  • Use properties of inequalities. (This objective is covered under solve inequalities as properties are used in solving)
  • Solve inequalities in one variable algebraically.
  • Solve absolute value inequalities
• Need help with the aligned of the array in the Properties of Inequalities box.
• Deleted the Graphic portion of the Section Exercises because graphing is covered later – due to rearrangement.

Chapter 3: Functions

Introduction to Functions

• Moved “the list of sections” (originally listed in the section  “Introduction to Functions” ) to the table of content.

The Rectangular Coordinate Systems and Graphs

• Moved “The Rectangular Coordinate System and Graphs” section (originally in Chapter 2 – Equations and Inequalities) to Chapter 3: Functions.

Domain and Range

• Deleted section exercises [latex]40-45, 48-51, 54[/latex], and  [latex]57[/latex]

Absolute Value Functions

• Deleted section exercises [latex]5[/latex] and  [latex]38[/latex]

Chapter 4: Linear Functions

• Added “Linear Equations in Two Variables” (originally in Linear Equations in One Variable – Equations and Inequalities.) to Chapter 4: Linear Functions.
• Moved “Systems of Equations in Two Variables” (originally in Chapter 11 – Systems of Equations and Inequalities) to Chapter 4: Linear Functions.
  • Learning Objectives and exercises were adjusted to match the new sections.
• Deleted “access online resource video section”

Introduction

• Footnote link removed, but footnote reference kept at the bottom of the page.

Linear Equations in Two Variables

• One objective changed:
  • Find a linear equation.  to Write a linear equation in two variables.

Linear Functions

• Moved some of the key concepts from Linear Functions to Linear Equations in Two variables – concepts pertaining to parallel and perpendicular.
• Removed the objectives and put in previous section (Linear Equations in Two Variables):
  • Determine whether lines are parallel or perpendicular.
  • Write the equation of a line parallel or perpendicular to a given line.

Chapter 5: Polynomial and Rational Functions

Rational Functions

• Need labels below each table
  • Remove links to figures after table titles are fixed
• Created new graphs for 2 Try it problems.
  • Need graph after try it “down 4 units” and try it #8 in show solution. Created graph with geogebra.
• Changed the graph in exercise #35 to the correct graph as found in precalculus book.

Chapter 6: Exponential and Logarithmic Functions

Graphs of Exponential Functions

• Created two exponential graphs that were added

Graphs of Logarithmic Functions

• Added heading one to learning objectives (Graphing Transformation of Logarithmic Functions).

Exponential and Logarithmic Equations

• In the problem, using the Formula for Radioactive Decay to Find the Quantity of a Substance,
  • How long will it take for ten percent of a 1000-gram (g) sample of uranium-235 to decay? I added (g).
  • After 10% decays, 900 grams are left.

Back Matter

Proofs, Identities, and Toolkit Functions

• Deleted Heron’s Formula, Properties of the dot product, Standard form of the Ellipse, Standard form of the Hyperbola, and their proofs.
• Deleted Trigonometric Identities, the Unit Circle, and the table of the values of the trigonometric functions.
