In this chapter you will learn:
- What a function is — domain, range, and the vertical line test
- How a function can grow or decline on an interval
- What makes a function even or odd, and how to determine it
- How graph transformations (shifts, reflections, stretches) work
- Properties of the quadratic function: vertex, axis of symmetry, direction of opening
- How to solve quadratic inequalities
- The interval method for solving polynomial inequalities
- Properties of the parabola and its geometric meaning
