We have three functions defined as follows:

1. $g(x) = x^3 - x$
2. $h(x) = (x^3 - x)^4$
3. $f(x) = 7(x^3 - x)^4$

Would you like to find derivatives, solve these functions for particular values of $x$, or explore any specific properties of these functions (such as critical points, maximums, minimums, etc.)?

Here are some potential next steps:

1. Would you like to differentiate $g(x)$, $h(x)$, or $f(x)$?
2. Would you like to expand $h(x)$ or $f(x)$ for simpler forms?
3. Are you interested in solving $g(x) = 0$, $h(x) = 0$, or $f(x) = 0$?
4. Do you need to evaluate these functions for specific values of $x$?
5. Should we analyze the graph or behavior of these functions?

Tip:

Always simplify a function before differentiating or integrating, as it makes the process more manageable!
