58 Chapter Review NEL Chapter Review Q: Is an inverse of a function always a function? A: No; if an element in the domain of the original function corresponds to more than one number in the range, then the inverse relation is not a function. 5, Examples 1, 2, and 3. • Try Chapter Review Questions 10 to 13. Q: What is a piecewise function? A: A piecewise function is a function that has two or more function rules for different parts of its domain. 6, Examples 1, 2, 3, and 4. Questions 14 to 17. consists of two pieces.
