Function: f(x) = 3x³ - 2x² + 5x - 7
Power rule application: d/dx(x^n) = nx^(n-1)
Constant rule: d/dx(c) = 0
Sum rule: d/dx(u + v) = u' + v'

Step-by-Step Differentiation:

First term: d/dx(3x³) = 3 × 3x² = 9x²
Second term: d/dx(-2x²) = -2 × 2x = -4x
Third term: d/dx(5x) = 5 × 1 = 5
Fourth term: d/dx(-7) = 0
Combined result: f'(x) = 9x² - 4x + 5

Mathematical Analysis:

Degree reduction: Original degree 3, derivative degree 2
Critical points: f'(x) = 0 → 9x² - 4x + 5 = 0
Quadratic formula: x = [4 ± √(16 - 180)] / 18
Complex roots: No real critical points
Function behavior: Always increasing

Example 2: Advanced Product Rule Mathematical Impact

Scenario: Differentiating f(x) = (x² + 3)(e^x)

Product Rule Mathematics:

Function: f(x) = (x² + 3)(e^x)
Product rule: d/dx(uv) = u'v + uv'
First function: u = x² + 3, u' = 2x
Second function: v = e^x, v' = e^x

Step-by-Step Application:

First term: u'v = 2x × e^x = 2xe^x
Second term: uv' = (x² + 3) × e^x = (x² + 3)e^x
Combined result: f'(x) = 2xe^x + (x² + 3)e^x
Factored form: f'(x) = e^x(2x + x² + 3)

Outer function: f(u) = sin(u), f'(u) = cos(u)
Inner function: g(x) = x² + 3x, g'(x) = 2x + 3

Step-by-Step Application:

Outer derivative: cos(x² + 3x)
Inner derivative: 2x + 3
Chain rule application: f'(x) = cos(x² + 3x) × (2x + 3)
Final result: f'(x) = (2x + 3)cos(x² + 3x)
