Overview
Grade 12 Advanced Functions, University Preparation (MHF4U)
D. Characteristics of Functions
61. 12AF.D3.2
61.2 Evaluating piecewise functions
Evaluating piecewise functions
What You'll Learn
Identify which sub-function to use based on domain intervals
Evaluate piecewise functions by substituting x-values into the correct piece
Interpret domain restrictions using inequality notation and interval notation
Determine outputs when x-values fall on boundary points of domains
What You'll Practice
1
Evaluating piecewise functions with two or three sub-functions
2
Working with domains defined by inequalities and interval notation
3
Handling boundary values and equal signs in domain conditions
4
Calculating outputs using various function types including polynomials and radicals
Why This Matters
Piecewise functions appear throughout calculus, economics, and real-world applications like tax brackets and shipping rates. Mastering how to evaluate them builds your ability to work with functions that change behavior based on different conditions.
