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}`
