inverse of f(x)=(-3x-13x)/(x+8)

inverse

f (x) = \frac{- 3 x - 13 x}{x + 8}

- \frac{8 x}{x + 16}

Solution steps

y = \frac{- 3 x - 13 x}{x + 8}

Replace

x

with

y

x = \frac{- 3 y - 13 y}{y + 8}

Solve for

y, x = \frac{- 3 y - 13 y}{y + 8}

- \frac{8 x}{x + 16}

ln (4 x^{4})

\frac{x ^{2} + 5 x + 4}{x ^{2} + 15 x + 56}

y = x^{2} + 4 x

cot (x)

y = x + 9
