Step-by-Step Guidance for Combining Functions (Calculus Study Prep)

Given the function $f(x) = (x^3 - 5)^4$, which of the following pairs of $u(x)$ and $v(x)$ is correct such that $u(v(x)) = f(x)$?

Suppose $u(x)$ and $v(x)$ are functions such that $u(x) = 2x + 1$ and $v(x) = x^2$. What is the value of $u(v(3))$?

Given the table below and knowing $u(x)$ is even and $v(x)$ is odd, what is the value of $v(v(-3))$? $x$ | $3$ | $5$ | $7$ | $9$ $u(x)$ | $5$ | $-7$ | $9$ | $-3$ $v(x)$ | $-7$ | $3$ | $-5$ | $9$
