inverse of f(x)=(6x)/(x^2+9)

inverse

\frac{3 ( - x ^{2} + 1 + 1 )}{x}, \frac{3 ( - - x ^{2} + 1 + 1 )}{x}

Solution steps

y = \frac{6 x}{x ^{2} + 9}

Replace

x

with

y

x = \frac{6 y}{y ^{2} + 9}

Solve for

y, x = \frac{6 y}{y ^{2} + 9}

\frac{3 ( - x ^{2} + 1 + 1 )}{x}, \frac{3 ( - - x ^{2} + 1 + 1 )}{x}
