To find the derivative of the function (f(x) = -2x^{-3} + x^2 - 7), you can use the power rule and the constant rule of differentiation. The derivative of a constant is zero, and for a term of the form (ax^n), the derivative is (anx^{n-1}). Applying these rules:
(f'(x) = \frac{d}{dx}(-2x^{-3}) + \frac{d}{dx}(x^2) + \frac{d}{dx}(-7))
(f'(x) = -2 \cdot (-3)x^{-4} + 2x^{2-1} + 0)
(f'(x) = 6x^{-4} + 2x)
Simplify the expression:
(f'(x) = \frac{6}{x^4} + 2x)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
