inverse of f(d)=(d-12)/(2d+1)

inverse

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

\frac{- 12 - d}{2 d - 1}

Solution steps

y = \frac{d - 12}{2 d + 1}

Replace

d

with

y

d = \frac{y - 12}{2 y + 1}

Solve for

y, d = \frac{y - 12}{2 y + 1}

\frac{- 12 - d}{2 d - 1}

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

f (x) = arcsec (x)

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

y = 3 x - 6
