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.

What is the value of F(-7) when F(X) = 3X - 5/4?

Describe the importance of using brackets when substituting values into the function F.

How do you express the inverse function of F in the form of F^(-1)(X)?

What is the final answer for the inverse function of F of X?

What is the result of G(3) if G(X) = √(19 - X)?

Explain the process to find FG(3) using the values from F and G functions.

Which values of X cannot be included in the domain of G?
