1.3: Linear Inequalities
This section is an important foundation for learning how to express intervals and sets fluently using words, set-builder notation, and interval notation. You will use the concepts you learn here to describe the solutions to inequalities. Similarly, we can use sets to describe the behavior of all types of functions. You will be required to use the notation and concepts presented here in many future units in the course, so it is vital to make sure that you achieve mastery of the techniques presented here to be successful in the coming sections on functions.
This refresher on solving linear inequalities allows you to practice describing solutions using interval notation, set notation, and graphs. You will also have a chance to practice solving compound linear inequalities.
This refresher on solving absolute value inequalities lets you practice writing solutions using interval notation. You will also practice graphical analysis of absolute value inequalities.
