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.
