Exploring Key Features of Functions

The video tutorial covers key features of functions, including exercises on evaluating function values, identifying domain and range, and understanding parent functions. It emphasizes using graphing calculators to visualize functions and solve problems. The tutorial also discusses the axis of symmetry and provides examples of different types of functions such as linear, quadratic, and exponential.
