Question

Find the derivative of f(x) =2x^2 -4x + 3

Answer 1

Derivatives

Find the derivative of the function:

$f(x)=2x^2-4x+3$

The following rules are applied:

$\begin{gathered} (x^n)^{\prime}=n\cdot x^{n-1} \\ (kx)^{\prime}=k \\ (k)^{\prime}=0 \end{gathered}$

Where k and n are constants.

Applying the rules:

$\begin{gathered} f^{\prime}(x)=2(2x)-4+0 \\ Operate\colon \\ f^{\prime}(x)=4x-4 \end{gathered}$
