derivative of

f (x) = \frac{4}{2 - x}

\frac{4}{( 2 - x ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{4}{2 - x})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 4 \frac{d}{d x} (\frac{1}{2 - x})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= 4 \frac{d}{d x} ((2 - x)^{- 1})

Apply the chain rule:

- \frac{1}{( 2 - x ) ^{2}} \frac{d}{d x} (2 - x)

= - \frac{1}{( 2 - x ) ^{2}} \frac{d}{d x} (2 - x)

\frac{d}{d x} (2 - x) = - 1

= 4 (- \frac{1}{( 2 - x ) ^{2}} (- 1))

Simplify

4 (- \frac{1}{( 2 - x ) ^{2}} (- 1)) : \frac{4}{( 2 - x ) ^{2}}

= \frac{4}{( 2 - x ) ^{2}}
