This packet continues to explore and deepen the understanding of functions and their characteristics (domain and range, decreasing, increasing and constant, max and min); operations with functions; piece-wise functions with graphing; difference quotient; and applications of functions (word problems). An interesting and challenging packet, it includes a detailed solution key and it is appropriate for Algebra 2 and Pre-Calculus. It could also be used for group work, for practice or for assessment.
