The function you provided is:

$f(x) = 2x^3 - 4x^2 - 10x + 20$

Would you like to:

1. Find the derivative $f'(x)$?
2. Determine the critical points and identify local maxima or minima?
3. Evaluate the function at specific values of $x$?
4. Find the roots (where $f(x) = 0$)?
5. Analyze the behavior of the function as $x$ approaches infinity or negative infinity?

Tip: Understanding the derivative of a function can help identify where the function increases or decreases, and find local maxima and minima.
