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

inverse

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

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

Solution steps

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

Replace

x

with

y

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

Solve for

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

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

f (x) = 4 e^{x} - e^{- x}

f (x) = 1 - 2 x^{2}

f (d) = \frac{d + 12}{2 d + 1}

f (x) = \frac{9 x}{x - 6}
