Define the domain and range of linear, quadratic, and square root functions. Graph linear, quadratic and radical functions. Identify a function given a graph, identify whether a function is one-to-one from it’s graph. Define a function using a table, words, and an algebraic expression. Module 4: Functions and Function Notation Graph linear equations and inequalities using tables, intercepts, and slope/ intercept formats. Writing equations of lines given points, words, and graphs. Module 3: Graph Linear Equations and Inequalities Solve linear inequalities including compound inequalities, and absolute value inequalities. Represent inequalities with intervals, and on a number line. Solve applications of linear equations including distance, rate, and time, area, volume, and perimeter, and temperature conversion. Solve linear equations that contain fractions, absolute value, and require the distributive property. Classify real numbers, use properties of real numbers. Module 1: Real Numbers and Algebraic Expressions A review of the order of operations with real numbers, and arithmetic with fractions. The specific learning outcomes covered in this course include: Module 0: Review The course is laid out over 15 modules including a review. The course is also fully integrated in our online homework platform, Lumen OHM. The text for this course is a “digital textbook” of a current, curated collection of OER resources with embedded video examples created by James Sousa ( ). The course covers one semester of Intermediate algebra for college students in developmental math. This course is available at no cost to SUNY students.Intermediate Algebra by Lumen Learning is a derivative work based on Developmental Math: An Open Program, provided by Monterey Institute of Technology and Education. Online Homework Manager (OHM): A flexible, LMS-integrated math homework engine with learning content and activities you tailor to fit your students’ needs. Math for Liberal Arts is available as an OHM course. Lumen’s online homework system, OHM, provides frequent practice, machine grading, and immediate feedback to help students learn and master math and other quantitative subjects. Content includes text, images, videos, assessments, directed feedback, practice questions, and other interactives that invite students to apply their knowledge and improve their understanding. 
Lumen OER courses apply learning science insights to engage students and better support the learning process. Primary source material for the course is Math in Society, by David Lippman. This course offers a complete set of resources including editable e-text with embedded videos and practice along with online assessments and powerpoint slides. Core material for each topic is covered in the main text, with additional depth available through exploration assignments appropriate for in-class, group, or individual investigation.
Emphasis is placed on the applicability of the mathematics.
The text is designed so that most chapters are independent, allowing the instructor to choose a selection of topics to be covered. This modular survey course focuses on developing math literacy and problem solving skills, exploring topics such as counting systems, problem solving, measurement, graph theory, fractals, set theory and logic, voting theory, growth models, finance, data collection, statistics, and probability.
