The function provided in the image is:

$f(x) = \frac{1}{x^3}$

This represents a rational function where the variable $x$ is raised to the power of 3 and then placed in the denominator.

Would you like me to:

1. Find the derivative of the function $f(x)$?
2. Find the integral of $f(x)$?
3. Discuss the asymptotes and behavior of the function?
4. Solve for specific values of $f(x)$?
5. Analyze limits at certain points?

Here’s a tip: Rational functions often have vertical asymptotes where the denominator equals zero. Be careful with division by zero when evaluating or analyzing functions like this one.
