In this article, we dive into the derivative of the function f(x) = 3x⁴ − 5x² + 2x, explaining not only the computation but also its significance and applications.", "## What is a Derivative?", "Before we compute the derivative, let’s recall what it means. The derivative of a function at a point represents the instantaneous rate of change of the function at that point — essentially, the slope of the function’s graph. In mathematical terms, if ( f(x) ) is a differentiable function, the derivative is written as ( f'(x) ) or ( \frac{df}{dx} ).", "## Computing the Derivative: Step-by-Step", "Given the function:\n[ f(x) = 3x^4 - 5x^2 + 2x ]", "We apply standard rules of differentiation, including:", "- Power Rule: ( \frac{d}{dx}[x^n] = nx^{n-1} )\n- Constant Multiplier Rule: ( \frac{d}{dx}[c \cdot f(x)] = c \cdot f'(x) )\n- Sum Rule: ( \frac{d}{dx}[f(x) + g(x)] = f'(x) + g'(x) )", "Let’s differentiate each term:", "1.

For example, if ( f(x) ) models displacement over time, ( f'(x) ) is instantaneous velocity.", "## Visual Guide: Linking the Derivative to the Graph", "Graphically, the graph of ( f'(x) = 12x^3 - 10x + 2 ) shows how the slope of ( f(x) ) changes across the domain. Local peaks and valleys in ( f'(x) ) correspond to inflection points in ( f(x) ), while where ( f'(x) = 0 ) indicates horizontal tangents (critical points).", "## Conclusion", "The derivative of ( f(x) = 3x^4 − 5x² + 2x ) is ( f'(x) = 12x^3 - 10x + 2 ).
