Find the Rate at Which the Function F (X) = X4 − 2x3 + 3x2 + X + 5 Changes with Respect to X. - Mathematics

Find the rate at which the function f (x) = x4 − 2x3 + 3x2 + x + 5 changes with respect to x.

Solution

$\text{ Rate } =f'(x)$
$= \frac{d}{dx}\left( x^4 - 2 x^3 + 3 x^2 + x + 5 \right)$
$= \frac{d}{dx}\left( x^4 \right) - 2\frac{d}{dx}\left( x^3 \right) + 3\frac{d}{dx}\left( x^2 \right) + \frac{d}{dx}\left( x \right) + \frac{d}{dx}\left( 5 \right)$
$= 4 x^3 - 2\left( 3 x^2 \right) + 3\left( 2x \right) + 1 + 0$
$= 4 x^3 - 6 x^2 + 6x + 1$
