Chapter 17.3
Graphing piecewise non-linear functions
What You'll Learn
Graph piecewise functions with nonlinear components like parabolas, cubics, and square roots
Apply domain restrictions to nonlinear functions and identify open vs. closed endpoints
Determine domain and range of piecewise nonlinear functions using graphical analysis
Graph absolute value functions by reflecting negative portions vertically
Express absolute value functions as piecewise functions with appropriate domains
What You'll Practice
1
Sketching piecewise functions with parabolas, cubics, reciprocals, and radical functions
2
Finding domain and range from graphs using interval and set notation
3
Converting absolute value functions into equivalent piecewise definitions
4
Graphing transformations of nonlinear functions with restricted domains
Why This Matters
Piecewise nonlinear functions model real-world situations where relationships change at different thresholdslike tax brackets, shipping rates, or water pressure at varying depths. Mastering these graphs builds your ability to analyze complex functions in calculus and applied math.
