Hello s883! 
It means to take the 4th derivative of the given function f(x) and then evaluate the resulting expression at x = -2. And I would probably put calculus questions in the calculus forum for next time

I assume you mean [itex]f(x) = 1/x^2 + 4x + 9 + x^4= x^{-2}+ 4x+ 9+ x^4[/itex].
Can you find f'(x) using the "power rule" ([itex](x^n)'= n x^{n-1}[/itex])?
What about f'' and f'''?
Now do f''''.
