Answer 2

It looks like you've provided two functions, A and B, in the form $f(x)$ where $f(x)$ is defined by an expression involving $x$. Let's go through each function and provide some information.

A) $f(-x) = x(x - 3)$ This function defines $f(x)$ in terms of $-x$, meaning it relates the input $-x$ to the output $x(x - 3)$. If we want to express $f(x)$ directly in terms of $x$, we substitute $-x$ with $x$: $f(x) = (-x)(-x - 3) = x(-x + 3) = -x^2 + 3x.$

B) $f(x) = x(x - 4)$ This function $f(x)$ is already expressed in terms of $x$, where the output is given by $x(x - 4)$.

If you have any specific questions about these functions or if you'd like further explanation or analysis, feel free to ask!
