inverse of f(x)=(-x-4)/(x+2)

inverse

f (x) = \frac{- x - 4}{x + 2}

\frac{- 4 - 2 x}{x + 1}

Solution steps

y = \frac{- x - 4}{x + 2}

Replace

x

with

y

x = \frac{- y - 4}{y + 2}

Solve for

y, x = \frac{- y - 4}{y + 2}

\frac{- 4 - 2 x}{x + 1}

f (x) = \frac{( 4 x - 3 )}{x + 5}

f (x) = \frac{3 x}{4 x - 1}

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

cos (\frac{3}{- 2})

f (b) = b^{2} + 5
