inverse of 2/(x^2+1)

Solution

inverse

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

Solution

\frac{2 - x}{x}, - \frac{2 - x}{x}

Solution steps

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

Replace

x

with

y

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

Solve for

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

\frac{2 - x}{x}, - \frac{2 - x}{x}

Popular Examples

domain of x^2-2x-2 domain

x^{2} - 2 x - 2

slope of y=-1/5 x-4 slope

y = - \frac{1}{5} x - 4
