What is the maximum value of the derivative of f(x)= 3x^2+x^3
son4ous [18]

Answer:

Maximum Value: ∞

General Formulas and Concepts:

<u>Calculus</u>

Basic Power Rule:

  • f(x) = cxⁿ
  • f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x² + x³

<u>Step 2: Find Derivative</u>

  1. Basic Power Rule:                    f'(x) = 2 · 3x²⁻¹ + 3 · x³⁻¹
  2. Simplify:                                    f'(x) = 6x + 3x²

<u>Step 3: Analyze</u>

We see that our derivative is the graph of some sort of parabola. The parabola would be opening upwards.

Therefore, the maximum value of the derivative would be ∞, as the parabola's output <em>y</em> infinitely increases.
