To compute $(f \circ g)(x)$, also known as the composition of functions $f$ and $g$, it means you are plugging the output of $g(x)$ into the function $f(x)$. In other words, $(f \circ g)(x) = f(g(x))$.

For example, if you have:

• $f(x) = 2x + 3$
• $g(x) = x^2 + 1$

Then: $(f \circ g)(x) = f(g(x)) = f(x^2 + 1) = 2(x^2 + 1) + 3 = 2x^2 + 2 + 3 = 2x^2 + 5$

Would you like to share the specific functions for $f(x)$ and $g(x)$, so we can find the exact composition for your case?

Here are 5 related questions to expand on this:

1. How do you find the domain of a composition of functions?
2. Can you reverse the composition and compute $(g \circ f)(x)$?
3. What is the difference between function composition and multiplication?
4. What happens if $f(x)$ and $g(x)$ are inverse functions?
5. How does the composition of functions relate to real-world problems?

Tip: Always check if both $f(x)$ and $g(x)$ are defined for the given input when computing compositions!
