Would you like help solving one or more of these problems, or would you like detailed solutions for all? Let me know where you'd like to begin!

### Follow-Up Questions:
1. Do you want help calculating function values for the first problem?
2. Would you like detailed explanations on function compositions, such as \( (g \circ f)(x) \) or \( (f \circ g)(x) \)?
3. Should we focus on one specific function composition exercise to work through step by step?
4. Would you like a refresher on how to solve function compositions in general?
5. Are you looking for solutions with a focus on specific exercises from the image?

### Tip:
When dealing with function compositions, remember that \( (g \circ f)(x) \) means applying \( f(x) \) first, then applying \( g \) to the result of \( f(x) \).

The user uploaded an image containing exercises related to functions and their compositions. The questions ask to compute the value of a function at certain points and to determine compositions of functions f(x) and g(x).

This page covers exercises on evaluating functions at specific values and determining the composition of functions. Key topics include function evaluation, function composition, and applying algebraic operations. Suitable for high school students, Grades 10-12.
