{ "item_title" : "A Simple Approach to Precalculus - Functions, Graphs, and Equations", "item_author" : [" Kunlektra Academic Publishing "], "item_description" : "A Simple Approach to Precalculus - Functions, Graphs, and Equations is a clear, practical, and beginner-friendly mathematics book designed to help learners master the essential foundations of functions, graphing, equations, and early precalculus. Written in simple language with step-by-step explanations, this book helps students move from basic math ideas into a stronger understanding of the coordinate plane, function notation, linear equations, quadratic equations, graph transformations, and simple mathematical modelling. It is ideal for lower secondary students, homeschool learners, classroom support, tutors, parents, and anyone looking for an easy math guide that makes functions and graphs easier to understand. This book builds confidence by showing mathematics in different ways: through words, tables, formulas, and graphs. Learners will understand how to plot points, read coordinates, find slope, graph linear functions, solve quadratic equations, interpret parabolas, and use equations to model real-life situations. Each topic is explained clearly, followed by worked examples, guided practice, review exercises, and step-by-step solutions. Inside this book, learners will discover:The meaning of functions, domain, range, and function notationHow to use tables, formulas, graphs, and words to represent functionsThe coordinate plane, ordered pairs, quadrants, distance, and midpointSlope, rate of change, and graph interpretationLinear equations in slope-intercept, point-slope, and standard formGraphing linear functions, parallel lines, and perpendicular linesQuadratic functions, parabolas, vertex, axis of symmetry, and interceptsSolving quadratic equations by factoring, square roots, and the quadratic formulaGraph transformations including shifts, reflections, and stretchesAbsolute value, step, piecewise, inverse, and composite functionsModelling real-life problems with functions, graphs, and equationsDesigned for learners who want mathematics made easy, A Simple Approach to Precalculus - Functions, Graphs, and Equations provides a strong bridge from basic algebra to higher-level precalculus. It is perfect for revision, independent study, homeschooling, tutoring, classroom learning, and exam preparation. Whether the learner is struggling with graphing, confused by function notation, or preparing for algebra, precalculus, and future calculus, this book gives a simple step-by-step path to understanding. With clear explanations, worked examples, practice exercises, and full solutions, it helps students build the confidence and skills needed for success in mathematics.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/889/036/9798890362773_b.jpg", "price_data" : { "retail_price" : "17.99", "online_price" : "17.99", "our_price" : "17.99", "club_price" : "17.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
