inverse of f(x)=(3x+1)/(8+5x)

inverse

f (x) = \frac{3 x + 1}{8 + 5 x}

\frac{1 - 8 x}{5 x - 3}

Solution steps

y = \frac{3 x + 1}{8 + 5 x}

Replace

x

with

y

x = \frac{3 y + 1}{8 + 5 y}

Solve for

y, x = \frac{3 y + 1}{8 + 5 y}

\frac{1 - 8 x}{5 x - 3}

in v erse \frac{1}{x ^{4}}

in v erse f (x) = 0.5 x + 4

d o main f (x) = 5 x + 6

in f l ec t i o n ln (7 - 6 x^{2})

a sy m pt o t es f (x) = \frac{x}{x ( x + 4 )}
