Sobel and Lerner provide teachers with a teachable text and students
with a readable text that will properly prepare them for future courses,
particularly precalculus. The text is designed specifically to ease
the transition to precalculus and directly involve the graphing calculator.
speaks to students in a relaxed, motivational, yet precise
manner.
 avoids “theoremproof” formula, often leading
up to important new concepts using plausible arguments or observations,
then stating results
 gently leads students into mathematical processes, resulting
in better understanding and a clearer appreciation of mathematics
includes special material devoted to directly supporting
topics in precalculus without covering the actual topics themselves.
interweaves a graphical emphasis throughout the text, teaching
students the structure of numerous fundamental and important curves.
 uses translations, reflections, expansions and contractions
to make available a wide variety of curves
 solves various types of equations in conjunction with
the graphs of the related functions, leading to a more mature understanding
of both the algebra and graphing
NEW—offers optional graphing calculator sections
with exercises, sometimes to verify what has been done by hand, other
times to produce graphs of more complicated equations, observations
and analysis.
contains over 500 display examples that demonstrate and
support mathematical developments, offering detailed, fully developed
solutions as models for section exercises.
integrates interesting application examples with full solutions
to spark students' interest for the exercise sets that follow.
includes Challenge and Critical Thinking problems
at the end of most sections to develop and/or enhance students' criticalthinking
skills.
reflects the growing popularity of Writing in Mathematics
by including Writing Assignments near the end of most section
exercise sets.
constructs a strong pedagogical framework composed of:
 marginal notes
 teaching notes
 caution items
 Testing Your Understanding sections
 chapter review exercises
 two chapter tests after each chapter review exercise
set—one requiring workedout solutions, the other multiple choice
