Understanding the Derivative f'(x) = 3(3x²) - 5(2x) + 2(1) - 0: A Step-by-Step Guide

When diving into calculus, one of the most essential concepts is derivatives—mathematical tools used to analyze how functions change. Today, we break down a specific derivative expression:

f’(x) = 3(3x²) − 5(2x) + 2(1) − 0
(Note: This simplifies to a polynomial function derived via differentiation rules.)

What Is f'(x)? Breaking Down the Expression

The expression:

f’(x) = 3(3x²) − 5(2x) + 2(1) − 0
is a direct application of differentiation. Let's simplify it step by step.

Key Insights

Start by expanding each term:

3(3x²) = 9x²
−5(2x) = −10x
+2(1) = +2
− 0 = 0

Putting it together:
f’(x) = 9x² − 10x + 2

This derivative represents the slope of the original function’s graph at any point x. It quantifies how fast f(x) is changing, vital in optimization, motion analysis, and real-world modeling.

How Is f’(x) Derived? The Differentiation Process

Although the simplified form is 9x² − 10x + 2, understanding the derivation process using the power rule reinforces mathematical intuition.

For a general quadratic function:
f(x) = ax² + bx + c
its derivative follows:
f’(x) = 2ax − b

In our specific case, after simplifying:

a = 9 → 2(9)x = 18x? Wait—hold on!

Wait—let’s clarify carefully.

Original expression:
f’(x) = 3(3x²) − 5(2x) + 2(1) − 0 = 9x² − 10x + 2

If we interpret the original phrasing as applying differentiation to 9x² − 10x + 2, then:

Using derivative rules:

d/dx [xⁿ] = n xⁿ⁻¹
d/dx [constant] = 0

So:

d/dx [9x²] = 18x
d/dx [−10x] = −10
d/dx [2] = 0
d/dx [−0] = 0

Thus:
f’(x) = 18x − 10
