Find f'(x).


Find f'(x).


A function is an expression of one variable in terms of another variable(s). It tells us how variables are associated with each other. The rate of change of one variable with respect to another variable is represented by the first derivative of a function. The expression for the derivative of a function {eq}f(x) {/eq} is {eq}f'(x) {/eq}.

1) Computing {eq}f'(x) {/eq} when {eq}f(x) = x^2 - 2x {/eq}:

$$\begin{align*} f'(x) & = \dfrac{d}{dx} (x^2-2x) \\[2ex] & = \dfrac{d}{dx} (x^2) -...
