The image contains a problem regarding composition of functions. It states the following:

Given:

• $f(x) = x^2$
• $g(x) = x - 1$

The task is to find $g(f(x))$.

To solve this:

1. Start with $f(x) = x^2$.
2. Now, substitute $f(x)$ into $g(x)$. This means replacing $x$ in $g(x) = x - 1$ with $f(x) = x^2$.

Thus: $g(f(x)) = g(x^2) = x^2 - 1$

So, the complete expression is: $g(f(x)) = x^2 - 1$

Would you like further clarification on this? Here are 5 related questions for further practice:

1. What is the composition of $f(g(x))$ for the same functions $f(x)$ and $g(x)$?
2. If $f(x) = 3x + 2$ and $g(x) = 2x - 5$, what is $g(f(x))$?
3. How do you find the inverse of a function, and what is the inverse of $g(x) = x - 1$?
4. What are the domain and range of the composed function $g(f(x))$?
5. How do we differentiate the composite function $g(f(x))$?

Tip: When composing functions, always substitute the entire function inside the variable of the other function, treating it as a replacement for the variable.
