inverse of f(x)=((2x-5))/(x+7)

inverse

f (x) = \frac{( 2 x - 5 )}{x + 7}

\frac{- 5 - 7 x}{x - 2}

Solution steps

y = \frac{2 x - 5}{x + 7}

Replace

x

with

y

x = \frac{2 y - 5}{y + 7}

Solve for

y, x = \frac{2 y - 5}{y + 7}

\frac{- 5 - 7 x}{x - 2}

f (x) = (x + 3) (x - 3)

f (x) = 3 (x - 2)^{3}

f (x) = - 6 x - 5

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

f (x) = 2 cos (4 x - π)
