Determine the domain and range for the square root function

The video tutorial covers the concepts of domain and range for a function, including how to determine when a function is increasing or decreasing, and whether it is even or odd. The instructor explains the parent graph and transformations, such as reflections over the x-axis and shifts. The domain is identified as non-negative values, while the range is from negative infinity to three. The video concludes with a brief mention of determining if the function is even or odd, which will be covered in a subsequent video.
