Functions: The Basics, Composites, and Inverse Functions

The video tutorial covers the function F, explaining how to substitute values into it and find F(-7). It then demonstrates how to express the inverse of function F. The tutorial proceeds to introduce function G and shows how to calculate the composite function FG(3). Finally, it discusses domain restrictions for function G, emphasizing the importance of avoiding negative values under the root symbol.
