derivative of

f (x) = x^{2} + 1

\frac{x}{x ^{2} + 1}

Solution steps

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

Apply the chain rule:

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

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

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

= \frac{1}{2 x ^{2} + 1} \cdot 2 x

Simplify

\frac{1}{2 x ^{2} + 1} \cdot 2 x : \frac{x}{x ^{2} + 1}

= \frac{x}{x ^{2} + 1}

x^{2} - 24 x - 12

f (x) = x^{2} + 3 x

f (x) = \frac{x + 1}{x - 1}

e^{x}

y = 3 x + 2
