It's all aBout you!Your Customized Math Textbook Program
Like what you see but not in the order that you want it? Customize your Holt McDougal Larson Algebra 1, Geometry, and Algebra 2 program through Custom Solutions.
Provide a truly customized experience for your district or school. Holt McDougal’s Custom Solutions go beyond the Student Edition—it also customizes the Teacher Edition, Ancillaries, ExamView Assessment Suite, and the Online Textbook.
Downloadable Spiral Review is organized by chapter and lesson and is correlated to state standards.
The Student eEdition is designed to allow
students to easily navigate the site.
A huge factor for choosing Houghton Mifflin Harcourt was that our team quickly became very excited to have the option of customization. We have been able to customize the scope and sequence of our text’s chapters so it truly fits our district curriculum mapfor Algebra 2, rather than having to change our map to fit the text.

Writing Equations for Quadratic Functions
Write the equation for the quadratic function whose graph is shown.
A Compare the given graph to the graph of the parent function f (x) = x 2 .
Complete the table below to describe how the parent function must be translated to get the graph shown here.
B Determine the values of h and k for the function g(x) = (x - h) 2 + k.
h• is the number of units that the parent function is translated horizontally. For a translation to the right, h is positive; for a translation to the left, h is negative.
k• is the number of units that the parent function is translated vertically. For a translation up, k is positive; for a translation down, k is negative.
So, h = and k = . The equation is .
REFLECT
4a. What can you do to check that your equation is correct?
4b. If the graph of a quadratic function is a translation of the graph of the parent function, explain how you can use the vertex of the translated graph to help you determine the equation for the function.
4c. Error Analysis A student says that the graph of g(x) = (x + 2) 2 + 1 is the graph of the parent function translated 2 units to the right and 1 unit up. Explain what is incorrect about this statement.

reflect Practice
Students actively participate in every aspect of a lesson. This interactivity promotes a deeper understanding of the mathematics.
Problem-solving connections help students pull together the mathematical concepts and skills taught in the unit and apply them to real-world situations.
Reflect questions challenge students to think about the mathematics that they are studying and share their understanding with the class.
On Core worktexts integrate the Standards of Mathematical Practice throughout the students’ learning, helping students master both content and practice standards.

Problem Solving ConnectionsWelcome Back! Elizabeth is an event planner who has been hired to plan a class reunion. The class has 275 people and 256 will be attending. Elizabeth must plan the seating, decorations, and food. She then needs to determine how much to charge each guest so that all costs are covered.

Writing Equations for Quadratic Functions
Write the equation for the quadratic function whose graph is shown.
A Compare the given graph to the graph of the parent function f (x) = x 2 .
Complete the table below to describe how the parent function must be translated to get the graph shown here.
B Determine the values of h and k for the function g(x) = (x - h) 2 + k.
h• is the number of units that the parent function is translated horizontally. For a translation to the right, h is positive; for a translation to the left, h is negative.
k• is the number of units that the parent function is translated vertically. For a translation up, k is positive; for a translation down, k is negative.
So, h = and k = . The equation is .
REFLECT
4a. What can you do to check that your equation is correct?
4b. If the graph of a quadratic function is a translation of the graph of the parent function, explain how you can use the vertex of the translated graph to help you determine the equation for the function.
4c. Error Analysis A student says that the graph of g(x) = (x + 2) 2 + 1 is the graph of the parent function translated 2 units to the right and 1 unit up. Explain what is incorrect about this statement.

Interact connect
reflect Practice
Students actively participate in every aspect of a lesson. This interactivity promotes a deeper understanding of the mathematics.
Problem-solving connections help students pull together the mathematical concepts and skills taught in the unit and apply them to real-world situations.
Reflect questions challenge students to think about the mathematics that they are studying and share their understanding with the class.
On Core worktexts integrate the Standards of Mathematical Practice throughout the students’ learning, helping students master both content and practice standards.
