In this video, you’ll learn how to find the domain and range of different types of functions step by step. We work through clear examples involving absolute value, square root, exponential, and logarithmic functions to help you understand how each function behaves.

By the end of this lesson, you’ll feel more confident identifying valid inputs (domain) and outputs (range) for a variety of functions. Perfect for Algebra 2 or Precalculus students!
