Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

$\displaystyle y = -\frac{x^4}{2} + 3x^3 - 2x - 12$

Step 2: Differentiate

Basic Power Rule: $\displaystyle y' = -\frac{4x^{4 - 1}}{2} + 3 \cdot 3x^{3 - 1} - 1 \cdot 2x^{1 - 1}$
Simplify Exponents: $\displaystyle y' = -\frac{4x^3}{2} + 3 \cdot 3x^2 - 1 \cdot 2$
Divide: $\displaystyle y' = -2x^3 + 3 \cdot 3x^2 - 1 \cdot 2$
Multiply: $\displaystyle y' = -2x^3 + 9x^2 - 2$
