inverse of (sqrt(x+4))/(x-9)

inverse

\frac{x + 4}{x - 9}

\frac{18 x ^{2} + 1 + 52 x ^{2} + 1}{2 x ^{2}}, \frac{18 x ^{2} + 1 - 52 x ^{2} + 1}{2 x ^{2}}

Solution steps

y = \frac{x + 4}{x - 9}

Replace

x

with

y

x = \frac{y + 4}{y - 9}

Solve for

y, x = \frac{y + 4}{y - 9}

\frac{18 x ^{2} + 1 + 52 x ^{2} + 1}{2 x ^{2}}, \frac{18 x ^{2} + 1 - 52 x ^{2} + 1}{2 x ^{2}}

f (x) = \frac{x}{3} + 10

\frac{x}{7} + \frac{2}{7}

f (x) = \frac{( 1 - 3 x )}{x + 1}

\frac{5}{3 x + 2}

\frac{3 x - 2}{5}
