It looks like you've provided three functions:

1. $F(x) = x + 5$
2. $g(x) = x^2 - 9$
3. $h(x) = x^2 - 10x + 7$

What would you like to do with these functions? You could be looking to:

• Find composite functions, like $(F \circ g)(x)$ or $(g \circ h)(x)$
• Perform operations on them (addition, subtraction, etc.)
• Evaluate them at specific values of $x$

Let me know what you'd like to explore! If you'd like further details or have any questions, feel free to ask.

Here are some related questions:

1. How do you find the composite function $(F \circ g)(x)$?
2. What would $g(x) + h(x)$ simplify to?
3. How would you factor the quadratic function $h(x)$?
4. What is the value of $F(x)$ at $x = 3$?
5. How can we find the intersection points of these functions?

Tip: When composing functions, make sure to substitute the output of one function as the input for the next!
