inverse of f(x)=(7x-1)/(2x+5)

inverse

f (x) = \frac{7 x - 1}{2 x + 5}

\frac{- 1 - 5 x}{2 x - 7}

Solution steps

y = \frac{7 x - 1}{2 x + 5}

Replace

x

with

y

x = \frac{7 y - 1}{2 y + 5}

Solve for

y, x = \frac{7 y - 1}{2 y + 5}

\frac{- 1 - 5 x}{2 x - 7}

f (x) = 3 - ln (x + 2)

f (x) = \frac{100}{x - 12} + 8

y = e^{x} + 2

(y + 5)^{2} + 8 x = 16

\frac{( - 16 + r )}{4}
