inverse of f(x)=(sqrt(x+3))/(x-2)

inverse

f (x) = \frac{x + 3}{x - 2}

\frac{4 x ^{2} + 1 + 20 x ^{2} + 1}{2 x ^{2}}, \frac{4 x ^{2} + 1 - 20 x ^{2} + 1}{2 x ^{2}}

Solution steps

y = \frac{x + 3}{x - 2}

Replace

x

with

y

x = \frac{y + 3}{y - 2}

Solve for

y, x = \frac{y + 3}{y - 2}

\frac{4 x ^{2} + 1 + 20 x ^{2} + 1}{2 x ^{2}}, \frac{4 x ^{2} + 1 - 20 x ^{2} + 1}{2 x ^{2}}

\frac{2}{3} x + \frac{1}{2}

f (x) = \frac{x - 4}{7}

- 1 - x + 3

f (x) = \frac{1}{2} x + \frac{9}{2}

f (x) = \frac{6 - 5 x}{7 x - 6}
