Find dy/dx (the derivative ) of f(x) = 4x
Shkiper50 [21]

Derivative are used to determine the nature of a function. The derivative of the function f(x) = 4x^2 is 8x

<h3>Derivative of a function</h3>

The formula for finding the derivative of a function is expressed as:

f'(x) = nax^n-1

Given the function expressed as:

f(x) = 4x^2

We are to find its derivative as shown:

f'(x) = 2(4)x^2-1
f'(x) = 8x^1 = 8x

Hence the derivative of the function f(x) = 4x^2 is 8x
