This document discusses parent functions and their transformations, as well as toolkit functions that students should know for pre-calculus. It lists linear, square root, quadratic, cubic, rational, logarithmic, exponential, absolute value, and quartic functions as toolkit functions. For each function, students should understand properties like the graph, domain and range, intervals of increase/decrease, extrema, intercepts, end behaviors, asymptotes, symmetry, and continuity. An example is provided for the quartic function.
