How do different parent functions differ? Linear to Constant? Quadratic to Cubic? Etc? When does a function translate vertically? Horizontally? Reflect? Stretch? Shrink? What are some patterns that are observed when different transformations are placed on certain parent functions? How are the attributes of each function changed when a transformation is applied to it? TEKS Knowledge & Skill Student Expectation TAKS OBJ The student defines functions, describes characteristics of functions, and translates among verbal, numerical, graphical, and symbolic representations of functions, including polynomial, rational, power (including radical), exponential, logarithmic, trigonometric, and piecewise-defined functions.

What are the domains and ranges of functions? How do domains change when functions are arithmetically combined or composed? What does the domain and range represent in a problem situation? What are inverse functions? How do graphs of inverse functions relate? Why are inverses functions one-to-one? What does it mean to be one-to-one?
